When It Comes to Polyp Diagnosis With CADx, Location Matters (Medscape)

A new study presented at the 2024 United European Gastroenterology (UEG) Week reveals that computer-aided diagnosis (CADx) systems perform differently depending on the region of the colon, with lower accuracy in identifying polyps in the proximal colon compared to the distal colon. Led by Dr. Tommy Rizkala of the IRCCS Humanitas Clinical and Research Center, the study analyzed 7,782 polyps ≤5 mm and highlighted that CADx systems show significantly lower specificity in the proximal colon, despite comparable sensitivity across regions. This finding raises concerns about using CADx tools beyond the rectosigmoid colon, suggesting the need for more advanced systems trained specifically on proximal colon lesions.
