Article Synopsis
  • * The study analyzed data from 1284 participants, finding that high BP variability is associated with various features of cSVD, including white matter hyperintensities and lacunae.
  • * Notably, younger adults (under 60) with high PP variability were found to have a significantly increased risk for severe cSVD, highlighting the need for monitoring BP variability in this age group.

Purpose: Pancreatic cancer is one of the most aggressive malignant tumors with poor prognosis. High-intensity focused ultrasound (HIFU) is an effective and safe treatment option for advanced pancreatic cancer, however, the survival time of patients after the treatment was different. So, the purpose of this study was to evaluate the relationship between the high-risk characteristics and prognosis of unresectable pancreatic cancer after HIFU treatment.

Objective: This study was performed to investigate the accuracy of conventional ultrasound (US), contrast-enhanced US (CEUS), and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) in assessing the size of breast cancer.

Methods: In total, 49 breast cancer lesions of 48 patients were included in this study. The inclusion criteria were the performance of total mastectomy or breast-conserving surgery for treatment of breast cancer in our hospital from January 2017 to December 2020 with complete pathological results, as well as the performance of conventional US, CEUS, and DCE-MRI examinations with complete results.

Article Synopsis
  • The study aimed to evaluate if contrast-enhanced ultrasound (CEUS) parameters could assess treatment response in advanced pancreatic cancer patients undergoing pulsed-wave high-intensity focused ultrasound (PW-HIFU).
  • Researchers recorded CEUS parameters, CA19-9 levels, and pain scores from 30 patients before and after PW-HIFU treatment, analyzing correlations with tumor characteristics and treatment energy.
  • Results showed a significant decrease in pain scores and CA19-9 levels post-treatment, with CEUS also helping to classify tumor blood vessel characteristics, indicating its potential for evaluating treatment effectiveness in this patient group.

Aim: To assess the feasibility and efficiency of contrast-enhanced ultrasound (CEUS) real-time guided fine needle aspiration (FNA) for sentinel lymph node (SLN) of breast cancer.

Materials And Methods: This retrospective study reviewed 21 breast cancer patients who scheduled for surgical resection performed CEUS real-time guided SLN-FNA and intraoperative SLN biopsy (SLNB). The success rate of CEUS real-time guided SLN-FNA was analyzed.

Myopericytoma is a rare perivascular tumor commonly arising in the superficial soft tissue and subcutaneous tissue of the distal extremities. We report the first case of myopericytoma occurring in the breast, focusing on the imaging and histopathological characteristics of the tumor. From an imaging perspective, myopericytoma presents a well-circumscribed, marked hypervascularity, and intense enhancement after injection of contrast material.

Objectives: To analyze the ability of thyroid ultrasound computer-aided diagnosis (CAD) detection software (AmCAD-UT; AmCAD BioMed Corporation, Taipei, Taiwan) to assist sonographers in diagnosing Thyroid Imaging Reporting and Data System grade 3 and 4 space-occupying lesions and to provide evidence for ultrasound doctors (UDs) to use the diagnostic recommendations of the AmCAD system to inform clinical decisions.

Methods: In group 1, a retrospective study was performed on 234 cases of thyroid lesions confirmed by surgical pathology. The sensitivities, specificities, and accuracies of the diagnoses determined by the same UD independent of the software (UD) and after consulting the CAD software (UD + CAD) and by the software alone (CAD) were compared.

Background: Staging diagnosis of liver fibrosis is a prerequisite for timely diagnosis and therapy in patients with chronic hepatitis B. In recent years, ultrasound elastography has become an important method for clinical noninvasive assessment of liver fibrosis stage, but its diagnostic value for early liver fibrosis still needs to be further improved. In this study, the texture analysis was carried out on the basis of two dimensional shear wave elastography (2D-SWE), and the feasibility of 2D-SWE plus texture analysis in the diagnosis of early liver fibrosis was discussed.

Objective: To determine the best shear wave elastography (SWE) quantitative parameters including the maximum elasticity (Emax), mean elasticity(Emean), minimum elasticity, standard deviation and ratio of Emean (Eratio) in assessing benign and malignant breast lesions.

Methods: Totally 302 breast lesions underwent conventional ultrasound and SWE. Each lesion was classified according to ultrasound Breast Imaging Reporting and Data System (BI-RADS).

The goal of this study was to determine whether a combination of shear wave elastography (SWE) quantitative parameters could improve the accuracy of ultrasonography in the differentiation of benign and malignant breast lesions. Two hundred seventy-nine breast lesions in 251 women were evaluated with ultrasonography and SWE; pathologic results of all lesions were available. Each lesion was classified according to the Breast Imaging Reporting and Data System (BI-RADS) for ultrasound.
