目的:探究MRI与CT在直肠癌术前评估的应用价值。方法:选取该院自2013年5月至2015年9月收治的直肠癌患者65例,分为CT组(32例)和MRI组(33例),分析在不同的分期中CT及MRI的应用价值。结果:CT的影像学资料中,总体准确度达72%(23/32)。MRI的影像学资料中,总体准确度达85%(28/33)。T分期中T1、T2、T3三个分期MRI的诊断预测值较CT高,差异明显(P<0.05)。结论:MRI与CT相比准确度及敏感度更高,基于实际临床治疗,二种成像方式可结合实际临床使用。
Objective: To explore the value of MRI and CT in the preoperative evaluation of rectal cancer. Methods: Totally 65 patients with rectal cancer admitted from May 2013 to September 2015 in our hospital were divided into two groups: CT group (32 cases) and MRI group (33 cases). CT and MRI were analyzed in different stages value. Results: The overall accuracy of CT imaging was 72% (23/32). MRI imaging data, the overall accuracy of 85% (28/33). T stage staging T1, T2, T3 three staging MRI diagnostic predictive value higher than CT, the difference was significant (P <0.05). Conclusion: The accuracy and sensitivity of MRI compared with CT are higher. Based on the actual clinical treatment, the two imaging modalities can be combined with the actual clinical use.
