MRI of the prostate: Convincing detection and analysis of prostate cancer

Axial T2 (upper left and right), contrast enhanced T1 (DCE, lower left) and DWI (lower right) MRI of the prostate of a 52-year-old patient with a Gleason Score of 4. T2 hypointensity in the middle peripheral zone on the right with corresponding hyperintense DWI signal and marked hypervascularization. Prostate Intelligence has detected (overlaid to T2 axial, upper left) and rated the lesion as AI-Likert 4.3. The AI assistant detected additional non suspicious nodular lesions in the central, transitional and left peripheral zones, respectively (overlaid to T2 axial, upper left). Prostate Intelligence quantified the prostate volume as 51 ml (not shown). Histopathology confirmed the lesion in the right peripheral zone malignant.

MRI of the prostate is an important area of oncological radiology. It takes years of radiological experience to distinguish malignant lesions from benign changes. Furthermore, prostate imaging is an excellent example of close collaboration between radiologists and clinicians. How should the MRI be evaluated in regard to the Gleason score? How stringent is the topographical depiction of the lesions? Which lesions are determined as biopsy targets?

It is with great pleasure that we present Prostate Intelligence, an AI assistant for the detection and analysis of prostate cancer in MR studies.

Why Prostate Intelligence matters and how it works

Prostate Intelligence helps detect and analyze prostate cancer in MR studies. The results are clearly structured with heat maps and tables and enable the selection of biopsy targets. The evaluation of the results is based on the PI-RADS classification. Prostate Intelligence helps radiologists and clinicians save time, particularly when it comes to organ and tumor segmentation. The interdisciplinary case discussions improve in quality.

Who benefits

Clinicians and radiologists through the detailed visualization and diagnosis of prostate cancer in comprehensive images.

Our own experience at Radailogy

Prostate Intelligence convinced us in many ways. The sensitivity, NPV and AUC are each reported as >90% at an AI score threshold of 3.5. According to the AI manufacturer, Lucida Medical, the specificity of at least 78% is only achieved with a Gleason score of 4. Our tests based on our own patient data even outperformed the manufacturer’s data with a Gleason score <4. We observed a high TN rate of >95%. The classification of prostate tumors is given as a five-point AI Likert scale and is based on the PI-RADS score. Prostate Intelligence automatically calculates the prostate volume. The segmentation work is also pleasingly detailed, saves time and provides precision for radiological diagnosis and knowledge transfer to clinicians and patients. Prostate Intelligence can be seamlessly integrated into your daily workflow.

Any medical professional can use Prostate Intelligence for each individual patient by quickly and easily uploading MRI studies of the prostate to Radailogy. Our telemedicine customers also use this AI assistant as a standard in daily practice to optimize their oncology workflow.

Faster diagnoses for the chest X-ray in words and pictures

Chest radiography of a 65 years old patient with symptoms of lower respiratory tract infection. Multiple lung opacities and consolidations are visible in projection to the lower lung lobes as well as the middle lobe. Rayscape correctly identifies all consolidations (red) and opacities (green). Rayscape rates the probability for viral disease as intermediate (3 out of 6) and correctly suggests bronchopneumonia as the differential diagnosis. In addition, some small lung lesions are reported (pink) that were initially missed by the radiologists.

Chest radiography is one of the most common radiological examinations of all, and it is also an essential first-line imaging modality in hospitals and doctors´ offices. The precision in reporting and the communication of results from radiologists to patients and clinicians are the most important success factors for any optimal discussion of findings and therapy.

It is with great pleasure that we present Rayscape, an AI assistant for chest radiography.

What Rayscape is and how it works

Rayscape increases accuracy in detecting 17 major thoracic pathologies.

Thoracic findings are reported and visualized in tabular form. For each finding, the true positive rate is presented as a degree of probability versus differential diagnoses, especially for pulmonary nodules, pneumonia, and mediastinal pathologies. The clear presentation of findings is a welcome support for knowledge transfer from radiologists to patients and doctors.

Who benefits

Patients, clinicians and radiologists by identifying the most important chest diseases and injuries with a clear presentation of the findings in words and pictures.

Our own experience at Radailogy

We tested Rayscape for several years and brought it to life with the manufacturer. We reviewed the performance data and compared it to our own observations:

Rayscape supports the detection of pulmonary nodules, pulmonary consolidation, pulmonary edema, pulmonary emphysema, interstitial lung disease, tuberculosis, pneumothorax, pleural effusion, atelectasis, cardiomegaly, hilar and mediastinal pathologies, diaphragmatic abnormalities, fractures, scoliosis, catheters and drains. From our point of view, Rayscape achieves the best results in the detection of pneumonia, including viral pneumonia with probability grading from 1 to 6, pulmonary nodules, pneumothorax, pleural effusions, cardiac decompensation, consolidations and atelectasis.

The performance

Rayscape has a high level of accuracy in detecting 17 major chest pathologies. Area Under the Receiver Operating Characteristics (AUROC) is highest for tuberculosis (99.1), pneumothorax (97.4), pulmonary edema (94.7), consolidations (94.6), lowest for interstitial lung disease (81, 5), scoliosis (82), diaphragmatic anomalies (85.4), and hilar and mediastinal pathologies (87.7).

MRI of the lumbar spine: CoLumbo with new features

T2 sagittal (left and middle) and T2 axial (right) MRI of the lumbar spine of a patient with back pain, lower limb weakness and paresthesia. Marked disc bulging (blue) and spinal canal stenosis at the level L2/L3, moderate disc bulging and spinal canal stenosis at the levels Th1-L2 and L4-S1. Left paramedian disc herniation (red), dural sac impingement (light blue) and recessal displacement of the left L4 nerve root at the level L3/L4. Foraminal stenosis and compression of the left foraminal nerves L3 and L4 (pink) at the levels L3-L5. Osteochondrosis Modic Type II at the levels L2/L3 and L4/L5.

With CoLumbo we have an excellent AI assistant for the assessment of the MRI of the lumbar spine. The latest release, now available on Radailogy, brings with it a variety of additional features for high-quality reporting of this common radiological examination. In particular, the description of foraminal stenoses and foraminal nerve impingement as well as the detection of osteochondrotic pathologies according to Modic are important.

It is with great pleasure that we present CoLumbo, an AI assistant for MRI of the lumbar spine.

Why CoLumbo is important and how it works

CoLumbo saves time and increases accuracy in the detection of the most common pathologies of the lumbar spine.

Lumbar spine MRI findings are reported and visualized. It assists in the knowledge transfer from radiologists to both patients and clinicians. In addition, all findings are written in comprehensive, standardized reports and can be used as an integral, automatically filling part of final documents.

Who benefits

Patients, clinicians, and radiologists by more detailed and more accurate diagnosis with subsequent decreased likelihood of suboptimal therapy or surgery. Accurate automatic measurements and clear colorful depiction reduce the need for measuring MRI findings by hand.

Our own experience at Radailogy

The AI ​​assistant supports the detection of disc herniation, disc bulging, central spinal canal stenosis, foraminal stenosis, nerve root impingement, reduced vertebral and disc height, hypo- and hyperlordosis, spondylolisthesis and pseudolisthesis as well as osteochondrotic pathologies according to Modic.

The scientific evidence

CoLumbo´s performance has been tested in clinical research with excellent results in accuracy for intervertebral disc detection and labeling (100%), for the detection of disc herniation (87%; 95% CI: 0.84, 0.89), extrusion (86%; 95% CI: 0.84, 0.89), bulging (76%; 95% CI: 0.73, 0.78), spinal canal stenosis (98%; 95% CI: 0.97, 0.99), nerve root compression (91%; 95% CI: 0.89, 0.92), and spondylolisthesis (87.61%; 95% CI: 85.26, 89.21), respectively.

RayscapeLungCT

Oncological lung CT: Common, important and always time-consuming

Chest CT of a patient with a history of colorectal cancer. In the preliminary study dated June 13, 2023, two pulmonary nodules were visible in the left lower lobe (left). Rayscape Lung CT indicates the diameter and volume of each mass. In the follow-up CT dated September 29, 2023, these nodules progressed by 79.8% and 27.9%, respectively, in diameter and by 211.3% and 20.4%, respectively, in volume. In addition, three new nodules can be found in the lower lobe plane shown. Rayscape Lung CT marks these three lesions as new and indicates their diameter, volume and morphology (right).

Lung nodules occur in more than two million people per year in Europe alone. At the same time, the mortality rate from lung cancer worldwide is around two million annually. Their increase is expected to be around 30% in 10-year intervals. These few numbers alone illustrate the high level of responsibility that radiologists bear when interpreting computed tomography of the thorax. And the time-consuming nature of this task is particularly noticable when it comes to assessing lung nodules in each individual patient using their comparative studies.

It is with great pleasure that we present Rayscape Lung CT, an AI assistant for the detection of pulmonary nodules in CT studies.

Why Rayscape Lung CT matters and how it works

Rayscape Lung CT identifies pulmonary nodules from 3 to 30 mm in diameter. An important function is the automated comparison of nodules in the follow-up from CT study to CT study.

The results are reported in tabular form and visualized within the CT images. Each individual nodule is described with its exact location, diameter, volume and especially its morphology. These clear reports are an essential support for the transfer of knowledge from radiologists to patients and clinicians. Rayscape Lung CT can be used both for individual patients and in full-scale oncology departments.

Who benefits

Patients, clinicians and radiologists by the reliable detection of pulmonary nodules with clear reports in tables and images. In both screening and therapeutic oncology settings, the AI ​​assistant with its precise analysis enables timely and individual treatment.

Our own experience at Radailogy

Rayscape Lung CT has high values ​​for PPV, NPV and sensitivity of more than 97% each in our own patient population. At Radailogy, sensitivity in the correct detection of pulmonary nodules is over 93%. Nodules are precisely located and described using the parameters diameter, volume and morphology. If requested, up to three CT studies are compared in the follow-up setting. New nodules are reported as such. In particular, the automated comparison in follow-up lung CTs saves us an amazing amount of time for each individual patient every day and provides us with the desired additional security in the completeness of our findings.

Rayscape Lung CT performs a risk analysis for each study based on the established Fleischer criteria. We recognize this addition as useful, but we have not often used it in daily practice when discussing findings with clinicians and patients.

As described, the AI ​​assistant detects lung nodules with high reliability. We found that primary tumors larger than 30 mm in diameter are not described in detail in the oncological follow-up. However, this is not the goal of the software formulated by the manufacturer.

Triaging acute strokes: Emergency radiology gets AI support

Non-enhanced cerebral CT of a 47-year-old patient with acute left sided paresthesia about 4 hours before the examination. Slightly low attenuation of the right lentiform nucleus and the right insular cortex is particularly visible when comparing the sides. No intracranial hemorrhage is visible (links). CINA-ASPECTS identifies the hypodensities and correctly assigns them to the lenticulostriatal territory (right, red). In addition, the results are tabulated, the ASPECTS is calculated as 8/10.

Time is Health: Our motto is particularly understandable when it comes to acute ischemic strokes. Every medical acute care unit knows what it means to accompany a large number of patients around the clock with the best diagnostic precision. Intracranial acute pathologies must be visualized quickly and safely.

It is with great pleasure that we present CINA-ASPECTS, an AI assistant for the detection of acute intracranial ischemia in CT studies.

Why CINA-ASPECTS matters abd how it works

CINA-ASPECTS was developed as a triage tool for emergency radiology. The AI assistant immediately reports suspected acute intracranial ischemia in CT studies and enables the prioritization of these patients. The AI assistant provides radiologists and emergency physicians with an outstanding presentation of the findings in words and images.

Any medical professional can use CINE-ASPECTS for each individual emergency patient by quickly and easily uploading cerebral CT studies to Radailogy. In medical institutions, this AI assistant can also do its work automatically in the background in order to fully exploit the desired triage potential.

Who benefits

The triage of acute ischemic strokes is essential for everyone involved, i.e., patients, clinicians and radiologists.

Our own experience at Radailogy

We were able to reproduce the statistical data of sensitivity of 76.6%, specificity of 88.7% and of accuracy of 87.0% given by the developer in our tests and partly worked out higher data for accuracy.

CINA-ASPECTS detects low attenuation of the supratentorial tissue and sulcal corticomedullar disorders. The eponymous topographical ASPECTS is used for the analysis: the supratentorial tissue is divided into ten regions of the middle cerebral artery supply per hemisphere to describe ischemia in one of the two hemispheres. The suspected pathological areas are marked in color and listed in a table with information on the mean density values ​​per region. From this, the ASPECTS for both hemispheres is calculated and given.

The developer cites as a limitation that older infarctions would not be correctly identified and describes the use of CINA-ASPECTS within 100 minutes of the clinical event as an essential inclusion criteria.

CINA-ASPECTS does not currently support the detection of posterior circulation ischemia (pc-ASPECTS). We expect this with the next upgrade.

We also evaluated CINA-ASPECTS together with two other AI assistants, CINA-ICH and CINA-LVO, which were developed to detect hemorrhagic and non-hemorrhagic strokes in CT studies. Find out more in our AI assistants!

Cerebral artery occlusion: Emergency radiology gets AI support

CT angiography of the skull base arteries in a 68-year-old patient with worsening right sided paresthesia. In the coronal reformation, a contrast loss of the M2 segment of the left middle cerebral artery is be seen. Peripherally adjacent there is a large older ischemic defect (left). CINA-LVO correctly detects the artery occlusion (right, red box).

Time is Health: Our motto is particularly understandable when it comes to acute ischemic strokes. In about 80% they are caused by intracranial arterial thrombi. Rapid diagnosis using CT angiography is therefore essential.

It is with great pleasure that we present CINA-LVO, an AI assistant for the detection of intracranial artery occlusion in CT angiographies.

Why CINA-LVO matters and how it works

As a triage tool for emergency radiology, CINA-LVO reports suspected acute cerebral artery occlusions in CT angiographies and enables these patients to be prioritized. The AI assistant provides radiologists and emergency physicians with clear pictures.

Any medical professional can use CINA-LVO for each individual emergency patient by quickly and easily uploading CT angiographies of the skull base arteries to Radailogy. In medical institutions, this AI assistant can also do its work automatically in the background in order to fully benefit from its triage potential.

Who benefits

The triage of arterial ischemic strokes is essential for everyone involved, i.e., patients, clinicians and radiologists.

Our own experience at Radailogy

CINA-LVO (Large vessel occlusion) detects occlusions of the distal intracranial internal carotid artery and the M1 and M2 segments of the middle cerebral artery in CT angiographies of the skull base arteries. The suspected arteries are indicated in axial and coronal MIPs.

We were able to understand most of the statistical data given by the developer for sensitivity of 97.9%, specificity of 97.6% and accuracy of 97.7%. This correlates with the developer’s statement that occlusions less than 1.5mm are not recognized.

It is reasonable to use CINA-LVO together with CINA-ICH and CINA-ASPECTS, which were developed to detect hemorrhagic and non-hemorrhagic strokes in CT studies. Find out more in our AI assistants!

Acute pulmonary embolism: Emergency radiology gets AI support

CT angiography of the pulmonary arteries of a 58-year-old patient with acute respiratory distress and right-sided chest pain (left). There is a slight contrast sparing in the peripheral branching of the right lower lobe artery, affecting the lateral and dorsal segments. CINA-IPE correctly detects the embolization (right, red box).

Time is Health: Our motto is particularly understandable when it comes to acute pulmonary embolism. Diagnosis with CT angiography of the pulmonary arteries is therefore urgent. The automated early detection of positive findings helps every medical acute care unit that knows what it means to take care of a large number of patients around the clock.

It is with great pleasure that we present CINA-IPE, an AI assistant for the detection of acute pulmonary artery embolism in CT angiographies.

Why CINA-IPE matters and how it works 

As a triage tool for emergency radiology, CINA-IPE reports suspected thrombosis of the pulmonary arteries in CT angiographies and enables these patients to be prioritized. The AI assistant provides radiologists and emergency physicians with a clear visual presentation of findings.

Any medical professional can use CINA-IPE for each individual emergency patient by quickly and easily uploading CT angiographies of the pulmonary arteries to Radailogy. In medical institutions, this AI assistant can also do its work automatically in the background in order to fully benefit from its triage potential.

Who benefits

The triage of acute pulmonary embolism is essential for everyone involved, i.e., patients, clinicians and radiologists.

Our own experience at Radailogy

CINA-IPE detects emboli of the central and paracentral pulmonary arteries with excellent certainty. The suspected arteries are labeled in axial MIPs.

We were able to confirm the statistical data given by the developer of sensitivity of 86.6%, specificity of 92.7% and accuracy of 90.0% in our clinical tests. We recognized uncertainties in the detection of peripheral thrombosis. This correlates with the developer’s statement that subsegmental artery emboli are not detected.

Acute cerebral hemorrhage: Emergency Radiology gets AI support

Non-enhanced cerebral CT of a 46-year-old patient after high-speed trauma. There is an acute subdural hemorrhage along the right frontal and parietal hemisphere (left). In particular, it is frontally surrounded by incipient edema and a slight contralateral midline shift can be seen. There is no intraventricular hemorrhage. There is no evidence of a parafalcine herniation.

CINA-ICH correctly and fully detects intracranial hemorrhage (middle). Bleeding volume is reported within the CT series and also tabulated (not shown). The slight contralateral midline shift is precisely measured (right).

Time is Health: Our motto is particularly understandable when it comes to head injuries and strokes. Every medical acute care unit knows what it means to accompany a large number of patients around the clock with the best diagnostic precision. Intracranial acute pathologies must be visualized quickly and safely.

It is with great pleasure that we present CINA-ICH, an AI assistant for intracranial hemorrhage detection in CT studies.

Why CINA-ICH matters and how it works

CINA-ICH was developed as a triage tool for emergency radiology. The AI assistant promptly reports suspected intracranial hemorrhages in CT scans and enables prioritization of these patients. The AI assistant provides radiologists and emergency physicians with an outstanding presentation of the findings in words and images.

Any medical professional can use CINA-ICH for each individual emergency patient by quickly and easily uploading cerebral CT studies to Radailogy. In medical institutions, this AI assistant can also do its work automatically in the background in order to fully benefit from its triage potential.

Who benefits

The triage of traumatic brain injury and hemorrhagic stroke is essential for everyone involved, i.e., patients, clinicians and radiologists.

Our own experience at Radailogy

We were able to study the performance of CINA-ICH in detail in extensive test series. On the one hand, we were convinced by the quick and clear presentation of findings and, on the other hand, by the low false-negative and false-positive rates in the detection of intracranial bleeding. This is consistent with the statistical data provided by the developer of sensitivity and specificity of more than 90% each, measured on the total cohorts.

The results are reported in detail. Bleeding is plotted in axial CT volumes. In addition, the data are processed in tabular form and include the parenchymal, sub- and epidural, subarachnoid and intraventricular bleeding volumes. Furthermore, midline shifts are measured.

The manufacturer describes the smallest bleeding with a volume of less than 3 ml and non-acute haemorrhage as a possible false-negative detection. At Radailogy, we have not observed any missed bleeding in our clinical testing.

We also evaluated CINA-ICH together with two other AI assistants, CINA-ASPECTS and CINA-LVO, which were developed to detect non-hemorrhagic strokes in CT studies. Find out more in our AI assistants!
