The same patient and study as in Figure 1. At the infrarenal level of the aorta, more prominent calcific atherosclerotic plaques are visible. The image shows a method of calculating TBR as a ratio of SUV in the aorta region of interest and SUV in the venous blood pool on the same level—in this case, the inferior vena cava was used. TBRmax at this level was about 1.01. All calculations were performed in OsiriX MD (Pixmeo SARL, Bernex, Switzerland).
