With a newly developed segmenting method, it is possible to configure large amounts of data from various imaging datasets automatically and with little expertise.

Low-dose CT screening for lung cancer does present risks of false-positives and over-diagnosis, but for heavy or ex-smokers, it is worth it.

DECT and electron density offers more accurate differentiation between metastatic and non-metastatic lymph nodes when compared to FDG PET/CT.

Novel deep learning model can provide needed information from multi-modal imaging even when some modalities are absent.

Whether a patient has a pulmonary embolism, a higher-than-normal D-dimer value can help identify patients for whom CTPA is most appropriate, alleviating some workload from emergency radiology.

By incorporating non-imaging data, the algorithm can effectively pinpoint which patients will need ICU intervention.

Low-dose CT for lung cancer screening offers significant benefits for detection and follow-up, but utilization, to date, has been low. Debra S. Dyer, M.D., chair of the American College of Radiology's Lung Cancer Screening 2.0 Committee discusses what the screening provides and the challenges to more widespread implementation.

New research shows radiologists – regardless of experience level – fall victim to inattentional blindness, overlooking obvious unrelated findings when they are trying to answer a specific diagnostic question.

For patients who have had viral symptoms for more than 48 hours, combining chest CT findings and CO-RADS classifications can effectively diagnose COVID-19-positive patients.

Study finds 84 percent of CT and ultrasounds in the emergency department do not follow ACR appropriateness criteria and cause downstream problems for patient care.

Approximately half of all patients who experience stroke, brain bleeds, or blocked blood vessels, identified on MRI or head CT in this study, had high blood pressure or type 2 diabetes.
