The benefits of contrast-enhanced ultrasound in the differential diagnosis of suspicious breast lesions.
Front Med (Lausanne)
December 2024
Department of Ultrasound, The Second Affiliated Hospital of Xi'an Jiaotong University, Xi'an, China.
Background: Contrast-enhanced ultrasound (CEUS) shows potential for the differential diagnosis of breast lesions in general, but its effectiveness remains unclear for the differential diagnosis of lesions highly suspicious for breast cancers.
Objective: This study aimed to evaluate the diagnostic value of CEUS in differentiating pathological subtypes of suspicious breast lesions defined as category 4 of US-BI-RADS.
Methods: The dataset of 150 breast lesions was prospectively collected from 150 patients who underwent routine ultrasound and CEUS examination and were highly suspected of having breast cancers.
Transcatheter Caval Implantation for Severe Tricuspid Regurgitation.
Curr Cardiol Rep
January 2025
Department of Cardiovascular Medicine, Heart Vascular & Thoracic Institute, Cleveland Clinic, 9500 Euclid Avenue, J2-3, Cleveland, OH, 44195, USA.
Purpose Of Review: We describe the evolution of caval valve implantation (CAVI) as a treatment for severe symptomatic tricuspid regurgitation (TR) in the high surgical risk patient.
Recent Findings: Surgical treatment of severe TR is often limited by the high surgical risk of the patients who tend to develop severe secondary TR. Coaptation, annuloplasty, and orthotopic replacement strategies are all limited by annular and leaflet geometry, prior valve repair, and the presence of cardiac implantable device leads.

A 4-year-old female spayed mixed-breed dog received enucleation surgery of the right eye in 2018 following the diagnosis of glaucoma. The patient was presented in 2021 for recurrent swelling of the right orbit. Ultrasound confirmed the presence of a cystic structure, and chemical ablation with 1% polidocanol (compounded, Stokes Pharmacy, Mt.

Magnetic resonance imaging (MRI) is a cornerstone of non-invasive diagnostics and treatment monitoring, particularly for diseases of the central nervous system. Although 1.5- and 3 Tesla (T) field strengths remain the clinical standard, the advent of 7 T MRI represents a transformative step forward, offering superior spatial resolution, contrast, and sensitivity for visualizing neuroanatomy, metabolism, and function.

January 2025
Adaptive Diagnostic and Interventional Imaging, Inserm, CHRU de Nancy, Vandoeuvre-lès-Nancy, France.
Objectives: This study compared the characteristics of lesions suspicious for hepatocellular carcinoma (HCC) and their LI-RADS classifications in adaptive statistical iterative reconstruction (ASIR) and deep learning reconstruction (DLR) to those of MR images, along with radiologist confidence.
Materials And Methods: This prospective single-center trial included patients who underwent four-phase liver CT and multiphasic contrast-enhanced MRI within 7 days from February to August 2023. The lesion characteristics, LI-RADS classifications and confidence scores according to two radiologists on the ASIR, DLR and MRI techniques were compared.
