直肠癌T分期应用3.0T高场磁共振的评估价值分析

Estimated Value Analysis of 3.0T High Magnetic Field Resonance of Rectal Cancer T Staging Application

目的探讨3.0T高场磁共振在直肠癌诊断及TNM分期评价中的价值。方法选择2013年1月—2014年12月来该院就诊的96例直肠癌患者作为研究对象,将患者随机分为对照组和观察组各48例,对照组患者采用1.5T磁共振检查,观察组采用3.0T高场磁共振检查,将结果与病理结果进行对比分析。结果对照组总诊断正确率为81.3%,T1分期正确率为40.0%,T2分期正确率为50.0%,T3分期正确率为90.6%,T4分期正确率为100%,观察组总诊断正确率为91.7%,T1分期正确率为66.7%,T2分期正确率为85.7%,T3分期正确率为97.0%,均明显高于对照组,差异有统计学意义(P<0.05)。结论 3.0T高场磁共振对于直肠癌的T分期诊断具有显著作用,值得临床推广应用。

Objective The value of 3.0T high magnetic field in the diagnosis of rectal cancer and TNM staging evaluation is discussed. Methods 96 cases of rectal cancer patients who were treated in the hospital from Jan 2013 to Dec 2014 were selected as research objects and were randomly divided into the control group and observation group with 48 cases in each group. 1.5T magnetic resonance inspection was used for the patients in control group and 3.0T high magnetic field resonance was used for the observation. the contrastive analysis was made on the results and pathology results. Results The total diagnosis accuracy of control group is 81.3%. T1 staging accuracy is 40.0%, T2 staging accuracy is 50.0%, T3 staging accuracy is 90.6%, and T4 staging accuracy is 100%. The total diagnosis accuracy of observation group is 91.7%. T1 staging accuracy is 66.7%, T2 staging accuracy is 85.7%, T3 staging accuracy is 97.0%. All of them are higher than those of the control group. The difference is of statistical significance（P〈0.05）. Conclusion 3.0T high magnetic field resonance has remarkable function to the T staging diagnosis of rectal cancer and is worthy of clinical application and promotion.
