Methods: This retrospective study reviewed the efficacy of MWA in treating thyroid nodules in patients with cosmetic problems who underwent MWA from January 2021 to May 2023. Patients were followed up at 1, 3, and 6 months after MWA.

Value of contrast-enhanced ultrasonography in microwave ablation treatment of symptomatic focal uterine adenomyosis.

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.

Baseline and contrast-enhanced ultrasound features of hepatic epithelioid angiomyolipoma.

Background: Recurrence or metastasis after surgery had been reported in hepatic epithelioid angiomylipoma (epi-AML). Most hepatic epi-AMLs were misdiagnosed with hepatocellular carcinoma or other hepatic tumors before surgery.

Objective: To describe the baseline and contrast-enhanced ultrasound (CEUS) features of hepatic epi-AMLs and to explore the potential ultrasonic features for prognosis.

Enhancement patterns of small hepatocellular carcinoma (≤ 30 mm) on contrast-enhanced ultrasound: Correlation with clinicopathologic characteristics.

Purpose: To analyze the correlation between enhancement patterns of small hepatic carcinomas (HCCs; ≤ 30 mm) on contrast-enhanced ultrasound (CEUS) and the clinicopathologic characteristics.

Methods: The retrospective study included 346 inpatients (288 males and 58 females) with 372 pathologically confirmed small HCCs between January 2017 and December 2018. All patients underwent CEUS examination before pathological examination.

Characterization of Early Hepatocellular Carcinoma and High-Grade Dysplastic Nodules on Contrast-Enhanced Ultrasound: Correlation With Histopathologic Findings.

Objectives: To explore the enhancement features of early hepatocellular carcinoma (HCC, including well-differentiated HCC and high-grade dysplastic nodules with a focus of HCC) and high-grade dysplastic nodules (HGDNs) on contrast-enhanced ultrasound (CEUS), correlated with the histopathologic findings.

Methods: This retrospective study enrolled 81 patients with 85 pathologically confirmed hepatic lesions (69 early HCCs and 16 HGDNs). All of the hepatic lesions were examined by CEUS with SonoVue (Bracco SpA, Milan, Italy) before surgery or biopsy.

Contrast-enhanced US-guided percutaneous biopsy of anterior mediastinal lesions.

Purpose: We aimed to explore the value of contrast-enhanced ultrasonography (CEUS) in guidance of percutaneous biopsy of anterior mediastinal lesions.

Methods: Ninety patients with solitary anterior mediastinal lesions (55 males, 35 females; mean age, 46±4 years) were included. Patients were randomly divided into CEUS group (n=45) and conventional ultrasonography (US) group (n=45).

Is Brachial Artery Blood Flow Measured by Sonography During Early Postoperative Periods Predictive of Arteriovenous Fistula Failure in Hemodialysis Patients?

Objectives: The aim of our study was to determine a brachial artery blood flow level measured by sonography during early postoperative periods that is predictive of arteriovenous fistula failure in hemodialysis patients.

Methods: Doppler sonography was used to estimate the blood flow in the brachial artery of 103 patients at 1 and 14 days after arteriovenous fistula creation. The performance of brachial artery blood flow during early postoperative periods for predicting fistula failure was evaluated, and optimal cutoff values were determined.

Value of Contrast-Enhanced Ultrasound in Guidance of Percutaneous Biopsy in Peripheral Pulmonary Lesions.

Objectives: To investigate the value of contrast-enhanced ultrasound (CEUS) in guidance of percutaneous biopsy in peripheral pulmonary lesions.

Methods: This study focused on 53 patients (male: 38, female: 15, and mean age: 55.7 years ± 10.

Differentiation of Renal Tumor Histotypes: Usefulness of Quantitative Analysis of Contrast-Enhanced Ultrasound.

Objective: The purpose of this study is to evaluate quantitative analysis of contrast-enhanced ultrasound (CEUS) in the differential diagnosis of renal tumor histotypes.

Materials And Methods: Between January 2010 and December 2013, 106 clear cell renal cell carcinomas (RCCs) (mean [± SD] diameter, 3.7 ± 1.

Papillary breast lesions on contrast-enhanced ultrasound: morphological enhancement patterns and diagnostic strategy.

Objectives: To identify features which determine the papillary nature of breast lesions by contrast-enhanced ultrasound (CEUS) based on morphological and pathological correlations, and predict which papillomas are malignant.

Methods: A retrospective review of 47 papillary lesions and 51 hypervascular benign abnormalities was performed. Enhancement patterns and diagnostic performance of CEUS were assessed.

Hepatic angiomyolipoma: contrast patterns with SonoVue-enhanced real-time gray-scale ultrasonography.

This study was conducted to retrospectively evaluate the pattern of contrast enhancement with SonoVue on gray-scale ultrasonography of hepatic angiomyolipoma (HAML). Imaging features of 33 pathologically proven HAML lesions in 33 patients who underwent baseline ultrasound and contrast-enhanced ultrasonography (CEUS) were assessed retrospectively. All lesions were enhanced in the arterial phase and showed whole-tumor filling in.

Quantitative evaluation of acute renal failure in rabbits with contrast-enhanced ultrasound.

Background: Assessment of perfusion in the early period of acute renal failure (ARF) is important, and can not be made by conventional ultrasound. The aim of this study was to prospectively test in a rabbit ARF model whether real-time contrast-enhanced ultrasound (CEUS) can quantitatively evaluate the hemodynamic changes of renal cortex in the early period.

Methods: The model of ARF was induced in 30 healthy New Zealand white rabbits (2.

Antiangiogenic effects of pazopanib in xenograft hepatocellular carcinoma models: evaluation by quantitative contrast-enhanced ultrasonography.

Background: Antiangiogenesis is a promising therapy for advanced hepatocellular carcinoma (HCC), but the effects are difficult to be evaluated. Pazopanib (GW786034B) is a pan-vascular endothelial growth factor receptor inhibitor, the antitumor effects or antiangiogenic effects haven't been investigated in HCC.

Methods: In vitro direct effects of pazopanib on human HCC cell lines and endothelial cells were evaluated.

[Quantitative evaluation of contrast-enhanced ultrasound in the early diagnosis of acute renal failure of rabbits].

Objective: To evaluate the early diagnostic value of contrast-enhanced ultrasound (CEUS) in acute renal failure (ARF) of rabbit.

Methods: The rabbit model of ARF was established by intramuscular injection of 50% glycerin (12 ml/kg) into the hind legs of 18 New Zealand rabbits. CEUS was performed for both kidneys before injection and 6 hours after the injection.
