Studies have suggested that nonpolypoid flat lesions -- defined as less than 3 mm in height above the surrounding colonic mucosa -- are more likely to contain cancerous tissue than polyps. However, these lesions are challenging to detect on both colonoscopy and CTC. Applying CAD software that's optimized for flat lesions could improve radiologists' diagnostic performance for flat lesions in CTC, particularly in screening populations, according to researcher Hiroyuki Yoshida, PhD.
Among 200 cathartic CTC studies that included confirmed flat lesions, the group's CAD system was able to substantially increase the sensitivity of human readers for detecting flat lesions in a screening population, Yoshida said.
How much did sensitivity improve? Attend this Wednesday morning session to get all of the details.
