AIM To investigate potential factors on MR imaging that could be used to predict migration of uterine fibroids post-UAE. METHODS AND MATERIALS We retrospectively reviewed patients referred for UAE having pre-procedural and 6 months post-procedural MRI, at a tertiary centre, over a 1-year period. Pre- and post-UAE images were reviewed in 64 women by two radiologists to identify the sub-type, dimensions, and infarction rate of each dominant fibroid. The shortest distance between the fibroid and the endometrial wall was measured to determine intramural fibroid movement. Paired sample T tests and two-sample T tests were used to compare between pre- and post-embolization variations and between migrated and non-migrated intramural fibroids, respectively. After preliminary results suggested potential predictors of intramural fibroids migration, we tested our findings against the non-dominant intramural fibroids in the same patients. RESULTS Review of images revealed 35 dominant intramural fibroids, of which eight migrated to become submucosal fibroids, while five were either partially or completely expelled. These 13 migrated fibroids had a shorter pre-procedural minimum endometrial distance (range 1-2.4 mm) and greater maximum fibroid diameter (range 5.1-18.1 cm), when compared to non-migrating fibroids. On image reassessment, the migrated non-dominant intramural fibroids had a minimum endometrial distance and maximum fibroid diameter within the same range. CONCLUSION Intramural fibroids with a minimum endometrial distance less than 2.4 mm and a maximum fibroid diameter greater than 5.1 cm have a high likelihood of migrating towards the endometrial cavity after UAE.

预测阿联酋的肌瘤迁徙影响：栓塞前MRI特征的作用。

目的探讨MR成像的潜在因素，这些因素可用于预测UAE后子宫肌瘤的迁移。方法和材料我们回顾性地回顾了在阿联酋三级中心接受手术前和手术后6个月MRI检查的阿联酋患者，为期1年。两名放射科医师对64名妇女的UAE前后图像进行了检查，以确定每种显性肌瘤的亚型，大小和梗死率。测量肌瘤和子宫内膜壁之间的最短距离，以确定壁内肌瘤的运动。配对样本T检验和两次样本T检验分别用于比较栓塞前后的变异以及壁内肌瘤和非壁内肌瘤的变化。在初步结果提示壁内肌瘤迁移的潜在预测因素后，我们针对同一患者的非优势壁内肌瘤测试了我们的发现。结果图像复查发现35种主要的壁内肌瘤，其中8例迁移成为粘膜下肌瘤，而5例被部分或完全排出。与非迁移性肌瘤相比，这13种迁移的肌瘤的术前最小子宫内膜距离较短（范围为1-2.4 mm），最大肌瘤直径较大（范围为5.1-18.1 cm）。在图像重新评估中，迁移的非优势壁内肌瘤在相同范围内具有最小子宫内膜距离和最大肌瘤直径。结论最小子宫内膜距离小于2.4毫米，最大子宫肌瘤直径大于5.1厘米的壁内肌瘤极有可能在阿联酋移植到子宫内膜腔。
