前瞻性地测定计算机辅助检测(CAD)是否有助提高CT结肠镜检查(CTC)对结直肠癌高危人群的诊断。因此,对连续170例病人均行CTC及结肠镜检查。采用结肠镜对所有≥6mm病灶行非盲法评价。分别计算每例病人≥6mm息肉和≥10mm息肉采用CAD及未用CAD的敏感度及特异度。用McNemar检验来比较使用CAD及未使用CAD的结果。
Prospectively determining whether computer-assisted detection (CAD) can help improve the diagnosis of colorectal cancer at high risk for people with colorectal cancer by CT colonography (CTC). Therefore, 170 consecutive patients underwent CTC and colonoscopy. Colonoscopy was used to evaluate all non-blind lesions ≥6mm. Were calculated for each patient ≥ 6mm polyps and ≥ 10mm polyps using CAD and unused CAD sensitivity and specificity. McNemar’s test was used to compare the results of CAD with and without CAD.
