【摘要】：目的比較MRI各成像序列對直腸癌T分期的效用及應(yīng)用價(jià)值。方法搜集經(jīng)手術(shù)確診的57例直腸癌患者行直腸MRI檢查。使用呼吸觸發(fā)脂肪抑制快速恢復(fù)快速自旋回波序列(FS-TSE)T2WI圖像、DWI,三維容積式內(nèi)插法屏氣檢查(3D VIBE)平掃及對比增強(qiáng)T1WI圖像,分別對病灶顯示清晰度、腸壁浸潤深度及是否侵犯漿膜層的顯示與手術(shù)結(jié)果進(jìn)行對比分析,分別評價(jià)各成像序列對結(jié)直腸癌T分期判斷的敏感性與準(zhǔn)確性。結(jié)果 FSTSE T2WI對直腸癌≤T2分期的準(zhǔn)確性、敏感性及特異性分別為84.2%(48/57)、30.8%(4/13)、100%(44/44),對直腸癌T3分期的準(zhǔn)確性、敏感性及特異性分別為84.2%(48/57)、100%(44/44)、30.8%(4/13);DWI對直腸癌≤T2分期的準(zhǔn)確性、敏感性及特異性分別為93.0%(53/57)、69.2%(9/13)、100%(44/44),對直腸癌T3分期的準(zhǔn)確性、敏感性及特異性分別為93.0%(53/57)、100%(44/44)、69.2%(9/13);增強(qiáng)VIBE對直腸癌≤T2分期的準(zhǔn)確性、敏感性及特異性分別為96.5%(55/57)、97.7%(43/44),對直腸癌T3分期的準(zhǔn)確性、敏感性及特異性分別為96.5%(55/57)、97.7%(43/44)、92.3%(12/13)。結(jié)論 MRI能較清楚地顯示直腸癌的范圍,能較準(zhǔn)確地對直腸癌進(jìn)行分期診斷;增強(qiáng)VIBE序列較其他序列對≤T2直腸癌分期判斷具有較高的準(zhǔn)確性及敏感性。
[Abstract]:Objective to compare the value of MRI sequences in T-staging of rectal cancer. Methods rectal MRI was performed in 57 patients with rectal cancer. Rapid recovery of fast spin echo sequence (FS-TSE) T2WI with respiratory triggered fat suppression (FS-TSE) was performed on DWI, 3D VIBE plain scan and contrast enhanced T1WI images were performed. To evaluate the sensitivity and accuracy of each imaging sequence in judging the T stage of colorectal cancer, the depth of invasion of the intestinal wall and the display of whether the invasion of serous layer were compared with the results of operation. Results the accuracy, sensitivity and specificity of FSTSE T _ 2WI for rectal cancer 鈮，
