To explore the safety and clinical efficacy of radiofrequency ablation (RFA) for papillary thyroid microcarcinoma (PTMC) located in the isthmus. This prospective study enrolled patients with single isthmus PTMC admitted to General Surgery Department of 983rd Hospital of Joint Logistic Support Force of PLA from 2017 to 2022. After ablation, the ultrasound and contrast-enhanced ultrasound (CEUS) were performed to follow up the outcomes at 1, 3, 6, 12, 18, and 24 months.

Introduction: Ultrasound imaging (US) is the method of choice to assess the canine prostate gland. Whilst recent studies have documented the role of castration in the development of prostatic neoplasia, little is known about parenchymal and perfusion features of the normal and abnormal prostate in neutered dogs. No data are available concerning prostatic changes after the first 90 days following castration.

Background: The contrast-enhanced ultrasound (CEUS) Liver Imaging Reporting and Data System (LI-RADS) classification offers a framework for risk stratification in evaluating liver lesions in patients at risk for hepatocellular carcinoma (HCC). However, its clinical utility in combined HCC-cholangiocarcinoma (cHCC-CCA) has been less extensively studied. The degree of tumor differentiation is clinically significant in determining prognosis, making the analysis of imaging features across different differentiation levels essential.

Department of Medical Ultrasound, West China Hospital of Sichuan University, 37# Guo Xue Xiang, Chengdu, 610041, Sichuan, China.
Purpose: This study aimed to explore a combined transrectal ultrasound (TRUS) and radiomics model for predicting tumor regression grade (TRG) after neoadjuvant chemoradiotherapy (NCRT) in patients with locally advanced rectal cancer (LARC).
Methods: Among 190 patients with LARC, 53 belonged to GRG and 137 to PRG. Eight TRUS parameters were identified as statistically significant (P < 0.
Application value of contrast-enhanced ultrasound in the preoperative evaluation of renal cell carcinoma histological classification and RENAL score.

Article Synopsis
- Renal cell carcinoma (RCC) is primarily treated through surgical options like radical or partial nephrectomy, and treatment decisions are based on histological classifications and the RENAL score, with contrast-enhanced ultrasound (CEUS) being a safer alternative to traditional imaging methods.
- A retrospective study at Lanzhou University Second Hospital evaluated how CEUS can help in preoperatively assessing RCC histological classifications and RENAL scores by analyzing tumor features in 248 patients undergoing surgery.
- Findings revealed that certain imaging features (hyperenhancement, heterogeneous enhancement, etc.) were significant indicators of clear cell RCC (ccRCC), suggesting CEUS has diagnostic efficacy comparable to contrast-enhanced CT in differentiating between cc
