Water/fat separate reconstruction for body quantitative susceptibility mapping in MRI.
Radiol Phys Technol
January 2025
Department of Radiology, Nagoya City University Graduate School of Medical Sciences, Nagoya, Japan.
This study aimed to investigate the cause of susceptibility underestimation in body quantitative susceptibility mapping (QSM) and propose a water/fat separate reconstruction to address this issue. A numerical simulation was conducted using conventional QSM with/without body masking. The conventional method with body masking underestimated the susceptibility across all regions, whereas the method without body masking estimated an equivalent value to the ground truth.

Section of Endocrinology, Geriatrics and Internal Medicine, Department of Medical Sciences, University of Ferrara, Ferrara, Italy.
Aim: This review aims to overview factors contributing to TAO development and addresses the targeted diagnostic work-up and treatment management in adult thalassemic patients.
Results: Osteoporosis management in Thalassemia is challenging because several factors contributing to its pathogenesis should be considered and controlled starting from child- hood. A multidisciplinary approach is crucial.
[The decline of analog radiological collection].
Andes Pediatr
October 2024
Facultad de Medicina, Universidad del Desarrollo, Santiago, Chile.
Throughout the 20th century, radiographs and fluoroscopies became essential elements to complete clinical evaluation. Images of the most relevant cases, together with their clinical records, were stored in the radiological collections of the hospitals. Over time, the need for physical space due to the emergence of new equipment, together with the digitization of radiographs and their digital storage, put an end to the collections, many of which were lost in a corner of modern X-ray services.

Department of Neurology, Sahlgrenska University Hospital, Gothenburg, Sweden.
Background And Purpose: Patients with active cancer face an increased risk of ischemic stroke. Also, stroke may be an initial indicator of cancer. In patients with large vessel occlusion (LVO) stroke treated with thrombectomy, analysis of the clot composition may contribute new insights into the pathological connections between these two conditions.
View Article and Find Full Text PDFAge-related hearing loss (ARHL) is considered one of the most common neurodegenerative disorders in the elderly; however, how it contributes to cognitive decline is poorly understood. With resting-state functional magnetic resonance imaging from 66 individuals with ARHL and 54 healthy controls, group spatial independent component analyses, sliding window analyses, graph-theory methods, multilayer networks, and correlation analyses were used to identify ARHL-induced disturbances in static and dynamic functional network connectivity (sFNC/dFNC), alterations in global network switching and their links to cognitive performances. ARHL was associated with decreased sFNC/dFNC within the default mode network (DMN) and increased sFNC/dFNC between the DMN and central executive, salience (SN), and visual networks.
