This study describes the prospective testing of a computer-aided diagnosis (CADx) system called POLyp Artificial Recognition (POLAR), developed for real-time diagnosis of diminutive colorectal polyps. The study was performed in 8 Dutch and 1 Spanish hospital with comparison of POLAR performance to that of 20 endoscopists.<\/p>\n\n\n\n
The primary endpoint was differentiation of diminutive adenomas and sessile serrated lesions (SSLs) from hyperplastic polyps. The POLAR system utilizes up to 3 images obtained by narrow-band imaging to reach diagnosis. <\/p>\n\n\n\n
POLAR reached a high-confidence diagnosis in 98.3% of lesions. The POLAR system correctly diagnosed 305 of 341 neoplastic lesions and 31 of 82 nonneoplastic lesions. The accuracy, sensitivity, and specificity of POLAR were 79.4%, 89.4%, and 37.8%, respectively, versus 83%, 92.4%, and 43.9% for the endoscopists. The sensitivity of SSL diagnosis was 17.1% with POLAR versus 58.6% by the endoscopists; leaving the SSLs out did not significantly change the performance numbers.<\/p>\n","protected":false},"excerpt":{"rendered":"
