【摘要】 目的探讨CT与MRI在直肠癌术前诊断与分期中的临床价值。方法收取直肠癌患者81例作为研究对象,对其CT与MRI影像学资料进行回顾性分析,对2种方法在直肠癌术前诊断及分期中的诊断效能进行考察与比较。结果 CT与病理T分期诊断符合57例,其中T1~2期11例、T3期28例、T4期18例,高估11例,低估13例;MRI与病理T分期诊断符合68例,其中T1~2期15例,T3期31例,T4期22例,高估7例,低估6例。CT与病理淋巴结诊断符合51例,MRI与术后病理淋巴结诊断符合65例。MRI诊断符合率显著高于CT检查,差异有统计学意义(P<0.05)。结论与CT相比,MRI在直肠癌术前诊断与分期中具有更高的准确率,具有更高的诊断价值。更多还原

【Abstract】 Objective To explore the clinical application value of CT and MRI in the diagnosis and staging of rectal cancer.Methods 81 patients with rectal cancer were selected and their CT and MRI data were retrospectively analyzed.Diagnosis value of the 2 methods for rectal cancer was observed and compared.Results There were 57 cases accordance with pathological diagnose of CT staging in T,including 11 cases of T1~2 stage,28 cases of T3 stage and 18 cases of T4 stage.11 cases were overestimated and 13 cases were underestimated.There were 68 cases accordance with pathological diagnose of MRI staging in T,including 15 cases of T1~2 stage,31 cases of T3 stage and 22 cases of T4 stage.7 cases were overestimated and 6 cases were underestimated.There were 51 cases and 65 cases accordance with pathological diagnosis respectively with CT and MRI lymph nodes diagnosis.Accordance rate of MRI was obviously higher than CT with statistically significance( P < 0.05).Conclusion MRI has better accordance rate in the diagnosis and staging of rectal cancer than CT,which has higher diagnosis value.更多还原
