Cervicothoracic volumetric bone mineral density assessed by opportunistic QCT may be a reliable marker for osteoporosis in adults.
Osteoporos Int
December 2024
Department of Diagnostic and Interventional Neuroradiology, Klinikum Rechts Der Isar, TUM School of Medicine and Health, Technical University of Munich, Ismaninger Str 22, 81675, Munich, Germany.
Unlabelled: This study aimed to validate the correlation between volumetric bone mineral density in the cervicothoracic and lumbar spine using measurements from opportunistic CT scans. The bone density assessment proved feasible, allowing us to propose optimal cut-off values for diagnosing osteoporosis and predicting vertebral fractures in the cervical and thoracic spine.
Objectives: To investigate the performance of cervicothoracic volumetric bone mineral density (vBMD), obtained through opportunistic quantitative computed tomography (QCT), in discriminating patients with/without osteoporosis and with/without vertebral fractures (VFs), using lumbar vBMD as the reference.
Age-dependent changes in diameters of abdominal visceral arteries in children.

Faculty of Medicine, Department of Pediatric Surgery, Van Yüzüncü Yil University, Van, Turkey.
Purpose: The diameters of the abdominal aorta and its branches are affected by demographic properties of patients like age, sex or body mass index. Some researchers use the body of the first lumbar vertebra (L1) as an anatomical indicator to create an exact standard for diagnosing arterial aneurysms or stenoses. In this regard, this work designed to uncover relations of abdominal visceral arteries with L1 in normal children using their abdominopelvic computed tomography images.

Material And Methods: Using multi-slice computed tomography (MSCT), the study examined the structure and relationships of key anatomical features, including the alveolar process, sinus wall thickness, and the position of the teeth in relation to the maxillary sinus.
Results: The results revealed that the lower wall of the maxillary sinus is predominantly formed by the alveolar process, with significant variability in wall thickness, especially between the central and lateral regions.
New wearable cardiac acoustic monitoring technology for evaluation of subclinical leaflet thrombosis after transcatheter aortic valve replacement.
Heart
December 2024
Interventional Center of Valvular Heart Disease, Beijing Anzhen Hospital Affiliated to Capital Medical University, Beijing, China
Background: Subclinical leaflet thrombosis (SLT) is a common complication after transcatheter aortic valve replacement (TAVR). Multidimensional CT (MDCT) is the main imaging mortality for the diagnosis of SLT but it enhances the risk of contrast-induced nephropathy. Our study aimed to use an innovative wearable acoustic cardiography (ACG) device to diagnose SLT as an alternative option.

Radiol Case Rep
February 2025
Department of Neurosurgery, Dr. Ram Manohar Lohia Institute of Medical Sciences, Lucknow, India.
Pulmonary venous developmental anomalies have historically been evaluated using echocardiography and catheter-based angiography. In recent years, however, multidetector CT angiography (MDCTA) and MR angiography have become increasingly important tools for detailed characterization of these anomalies. This case report provides an in-depth review of the radiologic findings in a 15-year-old patient diagnosed with the supracardiac type of Total Anomalous Pulmonary Venous Connection (TAPVC).
