Faster Acquisition and Improved Image Quality of T2-Weighted Dixon Breast MRI at 3T Using Deep Learning: A Prospective Study.
Korean J Radiol
January 2025
Department of Diagnostic and Interventional Radiology, University Medical Center Freiburg, Faculty of Medicine, University of Freiburg, Freiburg, Germany.
Objective: The aim of this study was to compare image quality features and lesion characteristics between a faster deep learning (DL) reconstructed T2-weighted (T2-w) fast spin-echo (FSE) Dixon sequence with super-resolution (T2) and a conventional T2-w FSE Dixon sequence (T2) for breast magnetic resonance imaging (MRI).
Materials And Methods: This prospective study was conducted between November 2022 and April 2023 using a 3T scanner. Both T2 and T2 sequences were acquired for each patient.
Debridement Technique for Single-Stage Revision Shoulder Arthroplasty.
JBJS Essent Surg Tech
January 2025
Shoulder and Elbow Service, Florida Orthopaedic Institute, Tampa, Florida.
Background: The incidence of revision shoulder arthroplasty continues to rise, and infection is a common indication for revision surgery. Treatment of periprosthetic joint infection (PJI) in the shoulder remains a controversial topic, with the literature reporting varying methodologies, including the use of debridement and implant retention, single-stage and 2-stage surgeries, antibiotic spacers, and resection arthroplasty. Single-stage revision has been shown to have a low rate of recurrent infection, making it more favorable because it precludes the morbidity of a 2-stage operation.

RMD Open
January 2025
Rheumatology, Medical University of Graz, Graz, Austria.
Objective: To test the reliability of the Outcome Measures in Rheumatology Giant cell arteritis (GCA) Ultrasonography Score (OGUS) and other composite scores in a patient-based exercise involving experts and non-experts in vascular ultrasonography.
Methods: Six GCA patients were scanned twice (two rounds separated ≥3 hours) by 12 experts and 12 non-experts. Non-experts received 90 min of theoretical and 240 min of practical training between rounds 1 and 2.
Article Synopsis
- Patients with HR+, HER2- breast cancers have lower responses to neoadjuvant therapy, and this study examines the effectiveness of neoadjuvant endocrine therapy (NET) in these patients.
- A total of 18,037 patients participated in the study, with 3,707 receiving NET and 14,330 receiving neoadjuvant chemotherapy (NAC), with NET patients being older on average (64.1 vs. 47.6 years).
- Results showed that node pathologic complete response (pCR) rates were 8.9% for NET compared to 14.9% for NAC, and axillary lymph node dissection (ALND) rates were also lower for NET patients (39.1%
Advancing high-resolution musculoskeletal ultrasound: a histology- and anatomy-driven approach for enhanced shoulder imaging. Part 2: Anterior and lateral shoulder.

Ultrasonography is a reliable imaging technique for the accurate diagnosis and evaluation of musculoskeletal disorders. Recent developments in ultrasound technology have significantly increased image resolution, making it possible to see anatomical features at almost microscopic dimensions. Current standards for standardized shoulder ultrasonography mostly depend on outdated machine types and configurations that may not fully utilize these high-resolution imaging capabilities.
