客观的。本研究的目的是确定是否可以通过子宫动脉栓塞后立即获得的钆增强 MR 图像上观察到的子宫肌瘤梗死率来预测肿瘤体积的缩小。 材料和方法。在我们的研究中，36 名患有症状性子宫肌瘤的女性成功接受了子宫动脉栓塞术。在手术前进行未增强和增强的 MR 成像，并在手术后 1 周、4 个月和 1 年重复进行。我们回顾性回顾了子宫动脉栓塞术后子宫肌瘤的增强磁共振图像。子宫动脉栓塞术后4个月，我们比较了完全梗塞的优势肌瘤患者的肿瘤体积缩小率与部分梗塞的肌瘤患者的肿瘤体积缩小率。结果。子宫动脉栓塞术后 1 周获得的增强 MR 图像显示，33 名女性 (92%) 的主要子宫肌瘤梗塞率达到 100%，其余 3 名 (8%) 的梗塞率达到 70-90%。他们还透露，在这些患者总共 204 个肌瘤中，199 个肌瘤（98%）实现了 100% 梗死。子宫动脉栓塞术后 4 个月获得的增强 MR 图像显示，完全梗塞的优势肌瘤 (n = 23) 的肿瘤体积缩小了 60% +/- 18%，而部分梗塞的肌瘤 (n = 5) 的肿瘤体积缩小了 35% +/- 27% (p = 0.0367)。 结论，钆增强 MR 成像是一种有用的诊断技术子宫动脉栓塞后的子宫肌瘤，因为它评估了栓塞肌瘤的梗塞程度，这对应于随后的肿瘤体积缩小。
OBJECTIVE. The purpose of this study was to determine whether tumor volume reduction can be predicted by the infarction rate of uterine fibroids as seen on gadolinium-enhanced MR images obtained immediately after uterine artery embolization.MATERIALS AND METHODS. In our study, 36 women with symptomatic uterine fibroids successfully underwent uterine artery embolization. Unenhanced and enhanced MR imaging was performed before the procedure and repeated at 1 week, 4 months, and 1 year after the procedure. We retrospectively reviewed enhanced MR images of uterine fibroids after uterine artery embolization. At 4 months after uterine artery embolization, we compared the rate of tumor volume reduction in patients with completely infarcted dominant fibroids with the rate of tumor volume reduction in patients with partially infarcted fibroids.RESULTS. Enhanced MR images obtained 1 week after uterine artery embolization revealed that 100% infarction rates of the dominant uterine fibroids were achieved in 33 women (92%), and 70-90% infarction rates were seen in the remaining three (8%). They also revealed that of a total of 204 fibroids in these patients, 100% infarction was achieved in 199 fibroids (98%). Enhanced MR images obtained 4 months after uterine artery embolization showed that tumor volume reduction of the completely infarcted dominant fibroids (n = 23) was 60% +/- 18%, whereas that of the partially infarcted fibroids (n = 5) was 35% +/- 27% (p = 0.0367).CONCLUSION, Gadolinium-enhanced MR imaging is a useful diagnostic technique for uterine fibroids after uterine artery embolization because it assesses the degree of infarction in the embolized fibroids, which corresponds to the subsequent tumor volume reduction.
