Figure 1

A maximum intensity projection TOF image (A) shows the vessel areas measurement at different level. The four orange lines (a-d) denote the position located at distal aorta (a), the proximal (b) and distal external iliac artery (EIA) (c), and the proximal deep femoral artery (DFA) (d), respectively. The left DFA (red arrow) is demonstrated at an axial image on TOF MRA and CTA (B-C).
