Lee JY, Chung HH, Kang SY, et al. - In order to find out the efficacy and safety of a new portable ultrasound-guided high-intensity focused ultrasound system (USgHIFU) with advanced targeting and beam steering technology for the treatment of uterine fibroids, researchers recruited a total of 59 uterine fibroids from 36 individuals (mean age, 44.9 ± 4.1 years) between November 2013 and November 2015. All individuals were treated with HIFU, with 3D electronic steering. They conducted MR imaging studies before HIFU, immediately after HIFU, and 1 month and 3 (or 5) months after the HIFU treatment. Between July and December 2017, long-term follow-up was performed (mean, 32.2 months). A portable USgHIFU with advanced functions was found to be safe and effective to treat uterine fibroids.
