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).
Photon-Counting Computed Tomography: Eleven Takeaways from a New Literature Review
May 27th 2025In a review of 155 studies, researchers examined the capabilities of photon-counting computed tomography (PCCT) for enhanced accuracy, tissue characterization, artifact reduction and reduced radiation dosing across thoracic, abdominal, and cardiothoracic imaging applications.
Can AI Predict Future Lung Cancer Risk from a Single CT Scan?
May 19th 2025In never-smokers, deep learning assessment of single baseline low-dose computed tomography (CT) scans demonstrated a 79 percent AUC for predicting lung cancer up to six years later, according to new research presented today at the American Thoracic Society (ATS) 2025 International Conference.
Can Emerging AI Software Offer Detection of CAD on CCTA on Par with Radiologists?
May 14th 2025In a study involving over 1,000 patients who had coronary computed tomography angiography (CCTA) exams, AI software demonstrated a 90 percent AUC for assessments of cases > CAD-RADS 3 and 4A and had a 98 percent NPV for obstructive coronary artery disease.
