目的 分析常规MRI检查以及扩散加权成像用于直肠癌术前分期的应用价值.方法 选取155例直肠癌手术患者为研究对象,所有患者均采用常规MRI检查以及扩散加权成像扫描,分析其扫描结果,并和病理结果进行对比.结果 常规MRI+DWI对患者T、N、M期的诊断结果和病理结果比较,差异不存在统计学意义(P>0.05).同时灵敏度、特异度、准确率、阳性预测值、阴性预测值与病理结果无统计学差异(P>0.05).结论 对于直肠癌手术患者,手术前常规MRI检查以及扩散加权成像扫描可以确定肿瘤的分期以及转移情况,为手术提供数据支持.
The Application Value of Routine MRI Examination and Diffusion-weighted Imaging for Preoperative Staging of Rectal Cancer
Objective To analyze the evaluation value of routine MRI examination and diffusion-weighted imaging for preoperative staging of rectal cancer.Methods 155 patients with rectal cancer surgery were selected as the study object,and all patients underwent conventional MRI and diffusion-weighted imaging scan,and compared with the pathological results.Results Routine MRI compared the diagnostic and pathological findings in T,N and M with DWI(P>0.05).There was no statistical difference between sensitivity,specificity,accuracy,positive predictive value,negative predictive value and pathological results(P>0.05).Conclusion For patients underwent rectal cancer surgery,conventional MRI examination and diffusion-weighted ima-ging can determine the stage and metastasis of the tumor,and provide data support for the surgery.
