Introduction: Microwave ablation (MWA) effectively treats adenomyosis, yet symptom recurrence remains challenging. Thus, our study aims to explore the independent risk factors related to symptom recurrence after MWA of symptomatic adenomyosis.
Material And Methods: Patients with symptomatic adenomyosis who received MWA treatment at our institute from June 2020 to June 2023 were retrospectively included.
Objectives: To establish a nomogram for differentiating malignant and benign focal liver lesions (FLLs) using ultrasomics features derived from contrast-enhanced ultrasound (CEUS).
Methods: 527 patients were retrospectively enrolled. On the training cohort, ultrasomics features were extracted from CEUS and b-mode ultrasound (BUS).

Ultrasound fusion imaging was used for detection, guidance, monitoring and immediate evaluation throughout the MWA procedures.
Background: Thermal ablation is routinely used for solitary colorectal liver metastases (SCLM), but the added value of adjuvant systemic therapy in SCLM remains unclear. This study aimed to compare the long-term outcomes for SCLM treated by ablation alone (AB) versus ablation plus systemic therapy (AS).
Methods: This multicenter retrospective study using nationwide data from fourteen institutions between October 2010 and May 2023, 369 patients with initial SCLM smaller than 5 cm, no extrahepatic metastases, and colorectal cancer R0 resection treated by thermal ablation were included.
Purpose: This study aimed to explore the reliability and stability of ultrasound-guided attenuation parameter (UGAP) values obtained by two measuring methods and different measuring times.
Methods: Patients who underwent liver UGAP examinations in our hospital from September 2022 to December 2022 were retrospectively analyzed. The clinical data and UGAP measurements results were collected.
Objective: To investigate the value of painless transvaginal four-dimensional hysterosalpingo contrast sonography (TV 4-D HyCoSy) in reducing venous intravasation and its influencing factors through a retrospective comparative study on conventional TV 4-D HyCoSy.

Purpose: This study evaluated the value of contrast-enhanced ultrasonography (CEUS) in the ultrasound-guided microwave ablation (MWA) treatment of symptomatic focal uterine adenomyosis.
Methods: This retrospective study was conducted between March 2020 and January 2023, enrolling 52 patients with symptomatic focal uterine adenomyosis who had undergone MWA. All patients were examined with CEUS before and after MWA.
Objective: This study aimed to retrospectively investigate the use of oral contrast-enhanced ultrasonography (O-CEUS) in assessing the thickness of the gastric wall for gastric cancer (GC) screening and to establish screening strategies for GC with different risk stratifications based on the gastric wall thickness.
Methods: From January 2015 to March 2020, people who underwent O-CEUS at the Physical Examination Center of our hospital with at least three years of follow-up were included in this study. The thickness of the gastric wall measured by O-CEUS was divided into three groups using 6 mm and 9 mm as cutoff values.
Purpose: To investigate the efficacy and safety of microwave ablation (MWA) assisted by ultrasound fusion imaging (FI) for primary and secondary liver cancers with a diameter of 3-7 cm.
Patients And Methods: A retrospective analysis was conducted on patients with primary and secondary liver cancers (3-7 cm) who underwent MWA with ultrasound FI assistance in our hospital from April 2020 to May 2022. Technical success, technique efficacy, local tumor progression (LTP), major complication, intrahepatic distant recurrence (IDR), and overall survival (OS) were assessed during the follow-up period.
Objectives: To construct a prognostic nomogram to predict the ablation zone disappearance for patients with papillary thyroid microcarcinoma (PTMC) after microwave ablation (MWA).
Materials And Methods: From April 2020 to April 2022, patients with PTMC who underwent MWA treatment were collected retrospectively. Ultrasound (US) or contrast-enhanced ultrasound (CEUS) was performed at 1 day, 1, 3, 6, 12, 18 and 24 months after MWA to observe the curative effect after ablation.
Purpose: The objectives were to investigate the safety and efficacy of thermal ablation as an alternative to liver transplantation for hepatocellular carcinoma patients with clinically significant portal hypertension (CSPH).
Materials And Methods: From July 2016 to September 2019, hepatocellular carcinoma patients with CSPH treated by liver transplantation (N=37) or thermal ablation (N=114) were enrolled. Cumulative intrahepatic recurrence, overall survival and major complications were compared by propensity score matching.
Objective: This study intends to compare the efficacy and safety between patients undergoing invasive isolation or monitoring measures and patients undergoing intra-operative contrast-enhanced ultrasound (CEUS) monitoring who underwent radiofrequency ablation (RFA) of hepatocellular carcinomas (HCC) adjacent to the gallbladder (GB).
Methods: We retrospectively assessed patients with HCC adjacent to the GB who underwent ultrasound-guided RFA. They were divided into two groups: group A was monitored under intra-operative CEUS, while group B was assisted by invasive auxiliary means.
Objectives: Accurate detection of carotid plaque using ultrasound (US) is essential for preventing stroke. However, the diagnostic performance of junior radiologists (with approximately 1 year of experience in carotid US evaluation) is relatively poor. We thus aim to develop a deep learning (DL) model based on US videos to improve junior radiologists' performance in plaque detection.

The treatment outcomes of ultrasound-guided percutaneous thermal ablation of hepatocellular carcinoma in the caudate lobe with and without fusion imaging (FI) assistance were evaluated and compared. Twenty-six patients with 28 tumors in the FI group and 8 patients with 8 tumors in the non-FI group were included. Although a higher number of tumors measured >20 mm in the FI group, the technique efficacy and local tumor progression were similar between the 2 groups (P > .

For the study group, the tumor and adjacent bile ducts were outlined on preprocedural MR images.
Neuromodulation by ultrasound (US) has recently drawn considerable attention due to its great advantages in noninvasiveness, high penetrability across the skull and highly focusable acoustic energy. However, the mechanisms and safety from US irradiation still remain less understood. Recently, documents revealed Piezo1, a mechanosensitive cation channel, plays key role in converting mechanical stimuli from US through its trimeric propeller-like structure.
