Broad view of heart shows otherwise missed pathology
Almost a quarter of all patients in a recent study who underwent CT angiography had findings outside the heart and great vessels, leading to several serious diagnoses being missed.
Almost a quarter of all patients in a recent study who underwent CT angiography had findings outside the heart and great vessels, leading to several serious diagnoses being missed. A broad viewing approach led to more workup and follow-up imaging.
Out of 6920 patients, 1642 had one or more extracardiac findings for a total of 1901 findings in the broad viewing scheme. Of all the patients, 16.2% had a finding necessitating therapy, workup, or follow-up. By engaging in just the focused viewing scheme, most therapy (90.9%), workup (64.1%), and follow-up (51.2%) needs were missed (AJR 2010;195:143-148).
Use of the focused approach resulted in fewer false-positive diagnoses, but five malignant tumors of the breast, 88 lung infiltrates, 43 cases of adenopathy, two cases of polycystic kidney disease, one breast abscess, and one case of splenic flexure diverticulitis were missed.
Study Examines CT-Based AI Detection of Incidental Abdominal Aortic Aneurysms
April 29th 2025The AI software Viz AAA offered a sensitivity of 87.5 percent in detecting abdominal aortic aneurysms on contrast-enhanced CT, according to new retrospective research presented at the American Roentgen Ray Society (ARRS) conference.

November 3rd 2020In this podcast episode, Dr. Shalom Kalnicki, from Montefiore and Albert Einstein College of Medicine, discusses the disparities minority patients face with cancer screenings and what can be done to increase access during the pandemic.
What is the Best Use of AI in CT Lung Cancer Screening?
April 18th 2025In comparison to radiologist assessment, the use of AI to pre-screen patients with low-dose CT lung cancer screening provided a 12 percent reduction in mean interpretation time with a slight increase in specificity and a slight decrease in the recall rate, according to new research.
Meta-Analysis Shows Merits of AI with CTA Detection of Coronary Artery Stenosis and Calcified Plaque
April 16th 2025Artificial intelligence demonstrated higher AUC, sensitivity, and specificity than radiologists for detecting coronary artery stenosis > 50 percent on computed tomography angiography (CTA), according to a new 17-study meta-analysis.
