[摘要] 目的 探討高分辨MRI對直腸癌分期及環(huán)周切緣的評估價(jià)值。 方法 對2014年1月~2016年8月期間在我院住院的直腸癌患者52例進(jìn)行高分辨MRI檢查,以術(shù)后病理檢查結(jié)果為金標(biāo)準(zhǔn),分析高分辨MRI對T分期、N分期以及環(huán)周切緣受累的診斷效果。 結(jié)果 高分辨MRI對T分期的診斷準(zhǔn)確率為84.62%,對N分期的診斷準(zhǔn)確率為71.15%,對環(huán)周切緣受累的診斷準(zhǔn)確率為94.23%。 結(jié)論 高分辨MRI對T分期與環(huán)周切緣受累的診斷準(zhǔn)確率較高,值得臨床推薦。

[Abstract] Objective To evaluate the value of high-resolution MRI in staging and circumferential margin of rectal cancer. Methods High resolution MRI was performed on 52 patients with rectal cancer who were hospitalized from January 2014 to August 2016 in our hospital. The diagnostic effects of high-resolution MRI on T-stage, N-stage, and circumferential margin involvement were analyzed, with the pathological findings as gold standard. Results The diagnostic accuracy of high-resolution MRI was 84.62% for T stage, 71.15% for N stage, and 94.23% for circumferential margin involvement. Conclusion High-resolution MRI has high diagnostic accuracy for T-stage and circumferential margin involvement, and is worthy of clinical recommendation.

我國直腸癌的發(fā)病率高于結(jié)腸癌,以低位直腸癌為主[1]。全直腸系膜切除術(shù)是中低位直腸癌的最常用術(shù)式,能將癌腫病灶完全切除,從而有效降低局部復(fù)發(fā)率,但需要以準(zhǔn)確的臨床分期作為手術(shù)實(shí)施的依據(jù)[2]。直腸癌位置低,容易被直腸指診及乙狀結(jié)腸鏡診斷。但因其位置深入盆腔,解剖關(guān)系復(fù)雜,手術(shù)不易徹底,術(shù)后復(fù)發(fā)率高,青年人發(fā)病率有升高的趨勢。對直腸癌進(jìn)行早期診斷,輔助臨床治療,對于改善預(yù)后具有重要意義。核磁共振(MRI)已應(yīng)用于全身各系統(tǒng)的成像診斷,效果較好,對比來說,其診斷效果比其他X線成像、二維超聲、核素及CT檢查準(zhǔn)確率高。高分辨MRI是一種新型的診斷技術(shù),逐步應(yīng)用于臨床診斷。高分辨MRI具有較高的軟組織對比分辨率,可多方位對病灶進(jìn)行掃查,可操作性也良好,是臨床診斷直腸癌的理想手段[3]。本研究即對高分辨MRI在直腸癌分期和環(huán)周切緣受累評估中的效果進(jìn)行分析,報(bào)道如下?!?br>
