We sought to investigate the differences of plaque characteristics in different femoral artery segments between males and females using magnetic resonance vessel wall imaging. The 3D-MERGE was acquired from the common femoral artery to the popliteal artery. We compared the differences of femoral artery plaque characteristics between men and women. Men had significantly larger area of lumen and wall, but smaller normalized wall index compared with women. Men have larger vessel size but lower plaque burden then women, more attention is needed to be paid to asymptomatic elderly women.
