From: Quantitative analysis of vascular signs on early postmortem multi-detector computed tomography
An axial thoracic image from early postmortem MDCT in a 55 -year-old man with cardiac arrest demonstrates high-attenuating wall signs in each ascending thoracic aorta (large white arrow) and descending thoracic aorta (large black arrow) with the wall attenuation of 74 HU, 70HU, respectively. Each ascending thoracic aorta and SVC has high-attenuated sedimentation with an attenuation difference of between the upper and lower halves of the lumen of 17 HU, 19 HU, respectively. Each descending thoracic aorta and abdominal aorta (not shown) are elliptical with minor/major-axial ratio of 0.76, 0.67, respectively. Presternal subcutaneous fat depth (white arrowhead) is 5-mm. A small black arrow in each ascending thoracic aorta and SVC indicates fluid-fluid level.
