Right coronary sinus of Valsalva pseudoaneurysm after a motorcycle accident: A case report.
Medicine (Baltimore)
January 2025
Department of Radiology, West China Hospital, Sichuan University, Chengdu, Sichuan, China.
Rationale: Traumatic pseudoaneurysm of the sinus of Valsalva (PSV) is a rare but life-threatening condition, often resulting from blunt chest trauma. Rapid progress and a high risk of rupture highlight the importance of prompt diagnosis and intervention. We present a case of a rare pseudoaneurysm linked to the right coronary sinus after blunt chest trauma.

From the Department of Radiology, Children's Hospital of Philadelphia, Philadelphia, PA.
Typical Meckel diverticulum on 99mTcO4- scintigraphy usually appears early in the dynamic imaging in the right lower quadrant of the abdomen, without change of location during the study. We report a case of pathology-proven Meckel diverticulum a 7-year-old boy, which appeared only on the later part of the 99mTcO4- study in the midline upper pelvis which gradually changed location during the study.

Department of Radiology, The Netherlands Cancer Institute, Amsterdam, The Netherlands.
Women with extremely dense breasts are at a higher risk of breast cancer, and the sensitivity of mammography in this group is reduced due to the masking effect of overlapping tissue. This review examines supplemental screening methods to improve detection in this population, with a focus on MRI. Morphologic techniques offer limited benefits, digital breast tomosynthesis (DBT) shows inconsistent results, and ultrasound (US), while improving cancer detection rates (CDR), results in a higher rate of false positives.

National Center for Magnetic Resonance in Wuhan, State Key Laboratory of Magnetic Resonance Spectroscopy and Imaging, Wuhan Institute of Physics and Mathematics, Innovation Academy for Precision Measurement Science and Technology, Chinese Academy of Sciences, Wuhan, 430071, China.
Emerging evidence suggests aberrant functional connectivity (FC) of brain networks in children, adolescents, and adults with autism spectrum disorder (ASD). However, little is known about alterations of dynamic FC in toddlers with ASD. The aim of this study was to investigate the characteristics of brain network dynamics in ASD toddlers.

Background: Motion correction methods based on slice-to-volume registration (SVR) for fetal magnetic resonance imaging (MRI) allow reconstruction of three-dimensional (3-D) isotropic images of the fetal brain and body. However, all existing SVR methods are confined to research settings, which limits clinical integration. Furthermore, there have been no reported SVR solutions for low-field 0.
