MSCT与MRI在结直肠癌术前分期诊断中的价值分析

目的探讨MSCT与MRI在结直肠癌术前分期诊断中的临床应用价值。方法选取确诊为结直肠癌的患者50例,对其进行MSCT和MRI扫描,将扫描结果与手术病理结果进行对比,观察MSCT与MRI对T分期的敏感度,以及对淋巴结分期的准确率。结果 MRI对T1-2分期的敏感度明显高于MSCT(P<0.05),MSCT与MRI对T3、T4分期的敏感度差异无统计学意义(P>0.05),MSCT和MRI对淋巴结分期的准确率分别为56.59%,58.50%差异无统计学意义(P>0.05),与手术病理分期比较,均无明显相关性(MSCT:P=0.288;MRI:P=0.208)。结论 MRI对结直肠癌T分期的准确性优于MSCT,MSCT和MRI对淋巴结分期的准确性一般。

Preoperative staging diagnosis of MSCT and MRI for colorectal carcinoma

Objective To study MSCT and MRI in the preoperative staging of colorectal carcinoma and its clinical value.Methods The MSCT and MRI manifestations of 50 patients with histopathologically proven colorectal carcinoma were included,scanning results and surgical pathology results were compared,observed sensitivity by MSCT and MRI for T staging,as well as for lymph node staging accuracy.Results MRI for T1-2 staging was more sensitive than MSCT(P < 0.05),MSCT and MRI on T3&T4 staging sensitivity have no significant difference(P > 0.05).MSCT and MRI for lymph node staging accuracy rate had no significant difference(P > 0.05) by 56.59% and 58.50%,and the comparison of surgical pathological staging were not significant correlation(MSCT:P=0.288;MRI:P=0.208).Conclusion MRI on T staging accuracy of colorectal carcinoma is better than MSCT,MSCT and MRI for lymph node staging accuracy is general.
