Anterolateral thigh (ALT) flap has been widely used in reconstructive surgery for head and neck region and the extremities. However, the difficulties during the dissection of this flap were often associated with various vascular anatomies and frequent intramuscular course of perforators [1]. In this study, using a novel differential subsampling with cartesian ordering (DISCO) contrast enhancement magnetic resonance angiography, the patterns of lateral circumflex femoral artery and its branches were clearly identified, and were consistent with operative findings. Therefore, DISCO imaging can be an accurate and compatible method for perforators imaging preoperatively prior to ALT flaps.
