【摘要】:目的 :探讨3.0TMR动态增强扫描(DCE-MRI)联合扩散加权成像(DWI)在评估诊断子宫内膜癌患者肌层浸润深度、宫颈侵犯和术前分期中的应用价值。方法:经病理证实的26例子宫内膜癌患者术前MRI影像资料,包括T_1WI、T_2WI、DCE-MRI和DWI序列,对照术后病理结果,评估应用DCE-MRI、DWI及DCE-MRI联合DWI法诊断子宫内膜癌肌层浸润、宫颈侵犯和术前分期的敏感性、特异性、准确率、阳性预测值、阴性预测值;比较不同成像方法对肌层浸润、宫颈侵犯和术前分期的准确率。结果:DCE-MRI、DWI及DCE-MRI联合DWI法判断肌层浸润深度的准确率分别为76.92%、73.08%和84.62%,DCE-MRI联合DWI法高于单独应用DCE-MRI和单独应用DWI法,差异具有统计学意义(P0.05);DCE-MRI、DWI及DCE-MRI联合DWI法判断宫颈侵犯的准确率分别为76.92%、73.08%和88.46%,DCE-MRI联合DWI法高于单独应用DCE-MRI和单独应用DWI法,差异具有统计学意义(P0.05);DCE-MRI、DWI及DCE-MRI联合DWI法判断分期的准确率分别为65.38%、53.85%和80.77%,DCEMRI联合DWI法高于单独应用DCE-MRI和单独应用DWI法,差异具有统计学意义(P0.05)。结论 :联合应用DCE-MRI和DWI较单独应用DCE-MRI或DWI可以更准确地进行子宫内膜癌术前评估,应常规应用于子宫内膜癌的术前检查。
[Abstract]:Objective: To investigate the dynamic enhanced 3.0TMR (DCE-MRI) combined with diffusion weighted imaging (DWI) in diagnosis of patients with endometrial carcinoma muscle layer infiltration depth, application value in staging and preoperative cervical invasion. Methods: 26 patients with pathologically confirmed endometrial cancer patients preoperative MRI image data, including T_1WI and T_2WI. DCE-MRI and DWI sequence, compared with postoperative pathological results, evaluate the application of DCE-MRI, DWI and DCE-MRI combined with DWI method for diagnosis of myometrial invasion of endometrial carcinoma, the sensitivity, the staging of cervical invasion and preoperative specificity, accuracy, positive predictive value, negative predictive value; comparison of different imaging methods on the infiltration of the muscle layer, accuracy the staging of cervical invasion and before surgery. Results: DCE-MRI, DWI and DCE-MRI combined with DWI method to determine the depth of myometrial invasion accuracy were 76.92%, 73.08% and 84.62%, DCE-MRI combined with DWI was significantly higher than that of DCE-MRI alone and DWI alone, the difference There was statistical significance (P0.05); DCE-MRI, DWI and DCE-MRI combined with DWI method to judge the accuracy of cervical invasion were 76.92%, 73.08% and 88.46%, DCE-MRI combined with DWI was significantly higher than that of DCE-MRI alone and DWI alone, the difference was statistically significant (P0.05); DCE-MRI, DWI and DCE-MRI combined with DWI method to determine the accuracy rate of staging were 65.38%, 53.85% and 80.77%, DCEMRI combined with DWI was significantly higher than that of DCE-MRI alone and DWI alone, the difference was statistically significant (P0.05). Conclusion: the combined application of DCE-MRI and DWI compared with the single application of DCE-MRI or DWI can evaluate the endometrial cancer to more accurately before, should check the routine application in endometrial carcinoma before the operation.
