DWI及其MRI增强扫描对宫颈癌同步放化疗疗效的评估价值

The Value of DWI and its MRI Enhanced Scan in Evaluating the Efficacy of Concurrent Chemoradiotherapy for Cervical Cancer

目的:探讨DWI及其MRI增强扫描对宫颈癌同步放化疗疗效的评估价值。方法:收集2015年8月—2017年8月期间在湖北省应城市人民医院就诊的经手术病理证实的宫颈癌患者30例为研究对象,所有患者在放疗的同时接受化疗,并且在治疗过程中接受弥散加权成像(DWI)检查和磁共振成像(MRI)检查。对患者检查进行疗效评估超声弹性成像检査和图像分析。结果:治疗一周后、两周后和治疗结束三个时间点的应变比值在CR组与PR组之间比较差异有统计学意义(P<0.05)。治疗一周后、两周后和治疗结束分别于治疗前比较,CR组与PR组的应变比值比较均差异有统计学意义(P<0.05)。结论:DWI及其MRI增强扫描对宫颈癌同步放化疗疗效的早期预测具有一定的评估价值。

Objective:To evaluate the value of DWI and its MRI enhanced scan in evaluating the efficacy of concurrent chemoradiotherapy for cervical cancer.Methods:Thirty patients with surgically-pathologically confirmed cervical cancer who were present in our hospital between August 2015and August 2017were collected.All patients received chemotherapy concurrently with radiotherapy and received diffusion-weighted imaging during the course of treatment.(DWI)examinations and magnetic resonance imaging (MRI)examinations.Efficacy assessments for patient examinations were performed using elastography and image analysis. Results:The strain ratios at one time after treatment,two weeks after treatment,and at the end of treatment were in the CR group and the PR group.The difference between the two groups was statistically significant (P<0.05).After one week,two weeks after the treatment and before the end of treatment,the strain ratios of the CR group and the PR group were significantly different (P<0.05). Conclusion:DWI and its enhanced MRI scans have certain value in the early prediction of the efficacy of concurrent chemotherapy and chemotherapy for cervical cancer.
