The Different Faces of Osler-Weber-Rendu Syndrome on Radiological Imaging

Three patients with a radiological diagnosis of OWRS were included (Table 1). [1][2]2][3] They underwent contrastenhanced computed tomography (CECT) and magnetic resonance imaging (MRI) examinations followed by vascular interventions at our hospital from February 2019 to September 2020. Computed Tomography and Magnetic Resonance Imaging AcquisitionCECT examinations of the abdomen and the pelvis were acquired using a Revolution EVO Gen 2 128-slice unit (GE HealthCare, Beijing, China).CT images were obtained with parameters of 120 kV and current in auto mode.Axial thin sections were acquired from the dome of the diaphragm to the symphysis pubis and the data were processed into multiplanar reconstruction (MPR) images with 5-mm slice thickness and three-dimensional images.The reconstruction interval was 0.625 mm.Approximately 80 mL of non-ionic contrast material (iohexol 350 mg iodine/mL; GE HealthCare, Milwaukee [WI], US) was administered with a power injector at a rate
