Objective: To investigate the prevalence of pelvic adhesions in patients with uterine fibroids after high-intensity focused ultrasound (HIFU) treatment, then analyze the influencing factors of pelvic adhesions.
Materials And Methods: From October 2010 to March 2020, a total of 2619 patients with uterine fibroids underwent either hysterectomy, myomectomy, or cesarean section in Suining Central Hospital of Sichuan province. Of the 2619 patients, 810 were excluded because of a documented history of either pelvic infections, endometriosis, prior abdominopelvic surgery, or gynecological malignancies; 1809 patients were enrolled and the data were retrospectively assessed for the prevalence and patterns of pelvic adhesions. Among them, 96 patients with uterine fibroids had had prior HIFU treatment (HIFU group), 1713 patients had not had HIFU or surgical treatments (control group).
Results: Among the 96 patients in the HIFU group, adhesions were detected in 42 patients, the incidence of pelvic adhesion being 43.75%; the 1713 patients in the control group, adhesions were detected in 619 patients, the prevalence of pelvic adhesion being 36.14%. No statistically significant difference in the incidence of adhesion between the two groups was observed ( = .132), no significant difference in location of pelvic adhesions between the two groups and no significant difference in the severity of adhesions between the two groups was observed ( > .05).
Conclusions: Based on our results with limited numbers, we concluded that HIFU treatment did not significantly increase the risk of pelvic adhesions.

Comparison of radiofrequency ablation, microwave ablation and high-intensity focused ultrasound for hepatocellular carcinoma: a retrospective study.

Background: The recommended first-line treatment for respectable hepatocellular carcinoma (HCC) is surgical resection, but local ablation has gained popularity as a safe alternative. This study aims to compare the effectiveness of radiofrequency ablation (RFA), microwave ablation (MWA) and high-intensity focused ultrasound (HIFU) as first-line treatments for HCC.
Methods: In this single-centre retrospective study, 352 patients receiving RFA, MWA, or HIFU as first-line treatment for HCC were included.

This review covers the theoretical background, pulse sequence considerations, practical implementations, and multitudes of applications of magnetic resonance acoustic radiation force imaging (MR-ARFI) described to date. MR-ARFI is an approach to encode tissue displacement caused by the acoustic radiation force of a focused ultrasound field into the phase of a MR image. The displacement encoding is done with motion encoding gradients (MEG) which have traditionally been added to spin echo-type and gradient recalled echo-type pulse sequences.

Purpose: In magnetic resonance-guided focused ultrasound (MRgFUS) breast therapies, the focal location must be characterized to guide successful treatment. Focal characterization is difficult because heterogeneous breast tissues introduce phase aberrations that blur and shift the focus and traditional guidance methods do not work in adipose tissues. The purpose of this work is to evaluate numerical simulations of MRgFUS that predict the focal location.

Objective: This study aimed to assess the effectiveness of conventional magnetic resonance imaging (MRI) combined with three-dimensional (3D) ultrasound for the preoperative prediction of nonperfused volume ratio (NPVR) in uterine fibroids after high-intensity focused ultrasound (HIFU) ablation.
Materials And Methods: In total, 178 patients who had undergone HIFU ablation therapy for uterine fibroids between July 2021 and August 2023 were enrolled. Baseline clinical, MRI, and 3D ultrasound parameters collected before and after HIFU ablation were analyzed.

Graves' disease (GD) is an autoimmune disorder with a high incidence rate, particularly affecting women of reproductive age. Current treatment modalities for GD carry significant disadvantages, especially for pregnant or nursing women. As a novel extracorporeal therapeutic technique, high-intensity focused ultrasound (HIFU) shows great promise for treating GD; however, its low treatment efficacy impedes clinical application.
