CT colonography also detects occult aortic aneurysms
Results of a study by Italian and U.S. investigators suggest CT colonography can simultaneously spot colorectal cancer and abdominal aortic aneurysms.
Results of a study by Italian and U.S. investigators suggest CT colonography can simultaneously spot colorectal cancer and abdominal aortic aneurysms. Findings could help the case for CTC as a cost-effective screening alternative to optical colonoscopy.
Dr. Perry J. Pickhardt, an associate professor of radiology at the University of Wisconsin Medical School in Madison, and colleagues designed a computer model that simulated CRC and AAA development in a hypothetical cohort of 100,000 Medicare patients aged 65 and older. The system compared costs and survival benefits for both screening methods. Among other findings, it showed that at 10-year screening intervals, CTC could yield 7027 life-years and save $1251 per life-year gained. Optical colonoscopy would extend lives by 995 fewer years and would save $147 less per life-year gained (AJR 2009;192[5]:1332-1340).
Can CT-Based AI Provide Automated Detection of Colorectal Cancer?
February 14th 2025For the assessment of contrast-enhanced abdominopelvic CT exams, an artificial intelligence model demonstrated equivalent or better sensitivity than radiologist readers, and greater than 90 percent specificity for the diagnosis of colorectal cancer.
Key Chest CT Parameters for Body Composition May be Prognostic for Patients with Resectable NSCLC
February 11th 2025A high intermuscular adipose index has a 49 percent increased likelihood of being associated with lower overall survival in patients with resectable non-small cell lung cancer (NSCLC), according to new research.
The Reading Room: Racial and Ethnic Minorities, Cancer Screenings, and COVID-19
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.
Comparative AI Study Shows Merits of RapidAI LVO Software in Stroke Detection
February 6th 2025The Rapid LVO AI software detected 33 percent more cases of large vessel occlusion (LVO) on computed tomography angiography (CTA) than Viz LVO AI software, according to a new comparative study presented at the International Stroke Conference (ISC).
New CT Angiography Study Shows Impact of COVID-19 on Coronary Inflammation and Plaque
February 5th 2025Prior COVID-19 infection was associated with a 28 percent higher progression of total percent atheroma volume (PAV) annually and over a 5 percent higher incidence of high-risk plaque in patients with coronary artery lesions, according to CCTA findings from a new study.
