Risk Factors and Computed Tomography Findings in COVID-19.

The images were acquired with a Siemens 256-slice multidetector tomograph (SOMATOM DEFINITION FLASH 128x2) following the recommended parameters for low-dose simple chest tomography. The chest topogram was acquired using 35 mA, 100 Kv, and 6 mm slices, then the chest tomographic slices holding inspiration in a cephalocaudal direction with 80 mA, 100 Kv, a duration of 2.24 seconds, a pitch of 1, and slices 1 mm with a total of 110 DLP, which is calculated with the conversion factor for thorax a total of 1.5 mSv. Multiplanar reconstructions with Kernel filters B26f, B50f, and B70 for mediastinum and lung, respectively, at 1 mm slices.
