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).
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.
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.
Can CT-Based AI Radiomics Enhance Prediction of Recurrence-Free Survival for Non-Metastatic ccRCC?
April 14th 2025In comparison to a model based on clinicopathological risk factors, a CT radiomics-based machine learning model offered greater than a 10 percent higher AUC for predicting five-year recurrence-free survival in patients with non-metastatic clear cell renal cell carcinoma (ccRCC).
Could Lymph Node Distribution Patterns on CT Improve Staging for Colon Cancer?
April 11th 2025For patients with microsatellite instability-high colon cancer, distribution-based clinical lymph node staging (dCN) with computed tomography (CT) offered nearly double the accuracy rate of clinical lymph node staging in a recent study.
