A 51-year-old man with severe multifactorial neurocognitive disorders subsequent to delirium, benzodiazepine withdrawal, and preexisting psychiatric illness was referred for 18 F-FDG PET/CT brain imaging in order to rule out an underlying neurodegenerative cause of the symptoms, particularly frontotemporal lobar degeneration. Imaging was impaired by severe motion artifacts, leading to a false-positive result. However, utilizing retrospective data-driven motion correction facilitated a change in diagnosis, ruling out the presence of neurodegenerative disease. The implementation of motion correction of the 18 F-FDG PET dataset proved crucial for the patient, as the exclusion of frontotemporal lobar degeneration formed the basis for continuing psychiatric and psychotherapeutic treatment.

Background: Evidence supporting surgery in elderly patients with distal radius fractures is limited, but displaced fractures may benefit from surgery. This study aimed to determine whether casting is noninferior to surgery for patients aged 65 years or older with substantially displaced intra-articular (AO type C) distal radius fractures.
Methods: This multicenter randomized controlled noninferiority trial included 138 patients (mean age 76 years, SD 6.

Background: Conventional cardiac magnetic resonance (CMR) examinations require patients to repeatedly hold their breath, which can reduce examination efficiency and pose challenges for patients unable to do so. This study aimed to demonstrate the feasibility and effectiveness of a full free-breathing CMR protocol in clinical practice.
Methods: Patients prospectively enrolled in this study underwent a full free-breathing CMR exam on a 3T scanner between June 1 and June 30, 2024.

Cardiovascular magnetic resonance (CMR) imaging is an established non-invasive tool for the assessment of cardiovascular diseases, which are the leading cause of death globally. CMR provides dynamic and static multi-contrast and multi-parametric images, including cine for functional evaluation, contrast-enhanced imaging and parametric mapping for tissue characterization, and MR angiography for the assessment of the aortic, coronary and pulmonary circulation. However, clinical CMR imaging sequences still have some limitations such as the requirement for multiple breath-holds, incomplete spatial coverage, complex planning and acquisition, low scan efficiency and long scan times.

Purpose: To develop a rapid 2D free-running myocardial mapping technique that is robust to through-plane respiratory motion.
Methods: A free-running golden angle radial sequence consisting of encoding and self-navigated auto motion calibration (SNAC) was developed. The encoding adopted inversion recovery (IR) prepared interleaved multi-slice acquisition with optimized inter-slice gap to ensure a uniform excitation of the middle slice regardless of through-plane respiratory motion.

In March of 2025, 145 attendees convened at the Hub for Clinical Collaboration of the Children's Hospital of Philadelphia for the inaugural International Society for Magnetic Resonance in Medicine (ISMRM) Body MRI Study Group workshop entitled "Body MRI: Unsolved Problems and Unmet Needs." Approximately 24% of the attendees were MD or MD/PhD's, 45% were PhD's, and 30% were early-career trainees and postdoctoral associates. Among the invited speakers and moderators, 28% were from outside the United States, with a 40:60% female-to-male ratio.
