Examples of CT values of lower leg muscles with lower (≤ 7) or higher (> 7) digital subtraction angiography (DSA) runoff score. a A 67-year-old man with mild peripheral arterial disease (PAD) (DSA score = 1). The first image shows a coronal view of lower extremity vessels. The second image is a localizer. The third column are axial computed tomography angiography (CTA) images, corresponding to the white lines in the localizer image. The fourth column shows the heatmaps of CT values of the muscles in the third column images. The red area of the color bar reflects high CT values and the blue reflects low values. b A 63-year-old woman with severe PAD (DSA score = 16). Images of b represent the same meaning as a
