摘要
目的:比较研究3.0TMRI和多层螺旋CT在直肠癌术前TN分期中的临床应用价值。方法:选择2016年4月~2018年4月期间某院收治的直肠癌患者54例作为研究资料,均于术前接受3.0TMRI和多层螺旋CT检查,回顾性分析两种检查方法的诊断准确性,依据手术病理结果评价两种方法N分期的应用价值。结果:MRI诊断T分期准确率88.89%与CT诊断比较明显更高(P<0.05);MRI诊断N分期准确率87.04%与CT诊断N分期准确率77.78%比较无明显差异(P>0.05)。结论:在直肠癌术前诊断中采用3.0TMRI和多层螺旋CT检查均具有较高的价值,其中3.0TMRI在T分期诊断中准确性相对较高,而N分期则无明显优势,因此实际诊断中需选择可靠的术前诊断方法。
Objective:To compare the clinical application value of 3.0 T MRI and multi-slice spiral CT in preoperative TN staging of rectal cancer. Methods:54 rectal cancer patients admitted to a hospital from April 2016 to April 2018 were selected as research materials. All patients underwent 3.0 T MRI and multi-slice spiral CT examination before surgery. The diagnostic accuracy of the two methods was analyzed retrospectively, and the application value of N staging of two methods was evaluated according to the pathological results of surgery. Results: The accuracy rate of MRI in diagnosing t-staging was 88.89%, which was significantly higher than CT diagnosis(P<0.05). There was no significant difference between MRI and CT in diagnosing N-staging accuracy of 87.04% and 77.78%(P>0.05). Conclusion:Both 3.0 T MRI and multi-slice spiral CT are of high value in preoperative diagnosis of rectal cancer, of which 3.0 T MRI has relatively high accuracy in T-staging diagnosis, while N-staging has no obvious advantage, so reliable preoperative diagnosis method should be selected in actual diagnosis.
