This study investigated the atherosclerotic plaque distribution in different femoral artery segments of asymptomatic old adults by 3D MR vessel wall imaging. We found that femoral artery plaque was prevalent in old adults, particularly in the segment of popliteal artery segment of femoral artery. After normalized the natural vessel size along femoral artery longitudinally, we found that popliteal artery segment showed the largest plaque burden as measured by NWI among all femoral artery segments. Our findings suggest that more attention needs to be paid to the popliteal artery segment of femoral artery in old adults for atherosclerotic disease care.
