Influences of screening magnetic resonance imaging parameters on high-intensity focused ultrasound outcome for adenomyosis

Nguyen Minh Duc, Huynh Quang Huy Department of Radiology, Pham Ngoc Thach University of Medicine, Ho Chi Minh City, Vietnam Abstract: Uterine adenomyosis is one of the most common benign pelvic diseases that adversely affects the quality of a woman’s life. High-intensity focused ultrasound is an effective noninvasive treatment option for symptomatic adenomyosis. Clinical studies showed that the prediction of immediate treatment outcome, defined as nonperfused volume ratio for adenomyosis, is one of the key parameters for determining the therapeutic efficacy. MRI parameters of adenomyosis in the screening phase, such as type, location, abdominal subcutaneous fat thickness, signal intensity of adenomyosis, size, number of foci inside the lesion, and perfusion, manifest the impact on nonperfused volume ratio. Therefore, in this article, we performed a literature review of the influential screening MRI parameters on the immediate high-intensity focused ultrasound outcome.
