To evaluate the potential of 3D TSE T2-weighted (SPACE) technique for assessing vessel wall of the superficial femoral artery at 3.0T. 15 healthy volunteers underwent 3D and 2D TSE T2-weighted (T2w) imaging of femoral artery. Muscle-lumen CNR and CNR efficiency was significantly higher with 3D SPACE when compared with the reference standard 2D T2w TSE. The measurements of wall volume (WV) and lumen volume (LV) by SPACE and 2D T2w TSE were highly correlated. 3D SPACE vessel wall imaging of the SFA with the SPACE technique is feasible at 3T clinical setting.
