MRI in Differentiating Leiomyoma Types in Women Undergoing Uterine Artery Embolization
Abstract
The aim of the study was to evaluate the efficiency of uterine artery embolization (UAE) by means of MRI, depending on their location, structure type and the presence of accompanying endometriosis Methods and materials. MRI (1.5 T) was performed in 20 women with leiomyomas (107 nodes) at the age of 41-46 years, presented for consideration for UAE before and 1 month after the manipulation. MRI was also performed in 6 months after the UAE in 8 women and in 12 months in 4 women. Results. Submucosal nodes were determined in 25% of cases, intramural - in 32% and subserosal - in 30.7%. Hyalinization of the nodes was noted in 44% of cases, the second most frequent type was node without signs of degeneration - 36%. The most prominent dynamics was noted in cellular leiomyoma type - the volume decrease was up to 50% in one month, 64% in 6 months and 75% in 12 months after UAE. In leiomyomas with hyaline, cystic or myxoid type of degeneration volume shrinkage was less prominent - 44%, 50% and 65% accordingly. Conclusion. MRI can provide us with precise information about location, size, structure and vascularization of leiomyomas before and after UAE. UAE efficiency depends on accompanying endometriosis and node structure.
