VC CAD software improves reader sensitivity

A large multireader trial performed by University of Chicago researchers has found that applying computer-aided detection (CAD) technology to virtual colonoscopy (also known as CT colonography or CTC) can improve reader sensitivity while maintaining a high level of specificity.

The research team evaluated a new CAD system (VeraLook, iCAD, Nashua, NH) with 19 nonexpert but qualified readers using a cohort of 100 CTC cases comprising varied polyp sizes, shapes, and histologies, according to presenter Dr. Abraham Dachman of the University of Chicago Medical Center.

The study found that CAD improved reader sensitivity by 5.5% for both small and large polyps, with only a 2.5% reduction in specificity.

"I am pleased that many readers were helped by using CAD," Dachman told AuntMinnie.com. "I think CAD will play a key role in the national implementation of CTC."
