Influence of Axial Rotation Between the Femoral Neck and Ankle Joint on Kinematics in Normal Knees: A Cross-Sectional Study.
J Am Acad Orthop Surg Glob Res Rev
January 2025
From the Department of Orthopedic Surgery, Faculty of Medicine, The University of Tokyo, Bunkyo, Tokyo (Dr. Kono, Dr. Taketomi, Dr. Kage, Dr. Inui, and Dr. Tanaka); the Department of Information Systems, Faculty of Engineering, Saitama Institute of Technology, Fukaya, Saitama (Dr. Yamazaki); the Department of Orthopedic Biomaterial Science, Osaka University Graduate School of Medicine, Suita, Osaka (Dr. Tamaki, and Dr. Tomita); the Department of Orthopedic Surgery, Saitama Medical University, Saitama Medical Center, Kawagoe, Saitama (Dr. Inui); and the Department of Health Science, Graduate School of Health Science, Morinomiya University of Medical Sciences, Suminoe, Osaka, Japan (Dr. Tomita).
Background: The effect of axial rotation between the femoral neck and ankle joint (total rotation [TR]) on normal knees is unknown. Therefore, this study aimed to investigate the TR effect on normal knee kinematics.
Methods: Volunteers were divided into groups large (L), intermediate (I), and small (S), using hierarchical cluster analysis based on TR in the standing position.
[The image is the key: unilateral absence of a branch of the pulmonary artery].

Departamento de Pediatría, Hospital Clínico Universitario San Cecilio, Granada, España.
Unlabelled: Unilateral absence of pulmonary artery (UAPA) is a rare and underdiagnosed entity. Due to its varied clinical expression, especially respiratory and most frequently associated with congenital heart disease, it can also present in isolation and remain asymptomatic for a long time. There is no consensus on its treatment, which is generally reserved for the presence of complications, mainly pulmonary hypertension, hemoptysis, or recurrent respiratory infections.

Department of Radiology, Peking University First Hospital, Beijing, 100034, China.
Objectives: To evaluate the performance of a 3D V-Net-based segmentation model of adrenal lesions in characterizing adrenal glands as normal or abnormal.
Methods: A total of 1086 CT image series with focal adrenal lesions were retrospectively collected, annotated, and used for the training of the adrenal lesion segmentation model. The dice similarity coefficient (DSC) of the test set was used to evaluate the segmentation performance.
Multi-Modality Imaging in Cardio-Rheumatology.
Curr Cardiol Rep
January 2025
Onassis Cardiac Surgery Center, Athens, Greece.
Purpose Of Review: Our purpose was to discuss the advantages and disadvantages of various noninvasive imaging modalities in the evaluation of cardiovascular disease (CVD) in patients with autoimmune rheumatic diseases (ARDs). The detailed knowledge of imaging modalities will facilitate the diagnosis and follow up of CVD in ARDs.
Recent Findings: Autoimmune Rheumatic Diseases (ARDs) are characterized by alterations in immunoregulatory system of the body.
Introduction: Computed tomography (CT) angiography is commonly utilized to quickly identify vascular injuries caused by blunt cervical trauma. It is often conducted alongside a cervical spine CT, based on established criteria. This study assessed the prevalence of cervical vascular injuries identified via CT angiography (CTA) in patients who had negative findings on cervical CT scans.
