摘要 目的分析MR成像用于直肠癌术前T分期的诊断效果及其价值。方法选取2017年2月至2020年3月直肠癌75例择期手术患者作为研究对象,患者均接受螺旋CT、MR成像检查,以手术病理结果为金标准,比较螺旋CT、常规MR平扫、MRI平扫+DWI+增强扫描3种方式的T分期结果,记录手术时间,4级评分法评价患者接受度。结果术后病理分期分别为:T1期10例、T2期15例、T3期28例、T4期22例。MRI平扫+DWI+增强扫描的T1~T4分期诊断准确率均高于螺旋CT、MR平扫,P<0.05。螺旋CT、MR成像的诊断用时分别为(23.5±7.6)分钟、(25.4±9.3)分钟,患者接受度分别为(4.7±0.8)分、(5.1±1.6)分,两组诊断用时、患者接受度相比,P>0.05。结论采取MRI平扫+DWI+增强扫描进行直肠癌术前T分期的综合诊断效能更佳,尤其是T4期准确率较高。
