Virtual colonoscopy tops conventional screening
The removal of lesions 6 mm or greater found by CT colonography screening is more cost-effective, safer, and just as clinically effective as colonoscopy or flexible sigmoidoscopy, according to a study in the June 1 issue of Cancer.
The removal of lesions 6 mm or greater found by CT colonography screening is more cost-effective, safer, and just as clinically effective as colonoscopy or flexible sigmoidoscopy, according to a study in the June 1 issue of Cancer.
Dr. Perry Pickhardt, an associate professor of radiology at the University of Wisconsin, and Dr. Cesare Hassan, a gastroenterologist in Rome, collaborated on the analysis. Their findings contradict previous ones showing that colonoscopy and flexible sigmoidoscopy of all sizes of polyps are more cost-effective than CT colonography. Earlier studies, however, ignored CT colonography guidelines on reporting only polyps greater than 5 mm. The cost per life-year gained from CT screening with a 6-mm threshold for follow-up was $4361 compared with $9180 for colonoscopy. The cost per life-year gained with CT screening with no polyp size threshold was $7138, compared with $7407 for flexible sigmoidoscopy.
Considering Breast- and Lesion-Level Assessments with Mammography AI: What New Research Reveals
June 27th 2025While there was a decline of AUC for mammography AI software from breast-level assessments to lesion-level evaluation, the authors of a new study, involving 1,200 women, found that AI offered over a seven percent higher AUC for lesion-level interpretation in comparison to unassisted expert readers.
