In Non-Contrast Enhanced MR Angiography (NCE-MRA), accelerated scanning helps to add into established clinical routine protocol for screening and follow-up. Compressed sensing (CS) is a promising technique to accelerate scanning for NCE-MRA which has sparse image. In this work, the combination of CS and parallel imaging was applied to NCE-MRA and demonstrated feasible. Volunteer scan was performed as acceleration factor of CS+PI was changed. The CS +PI sequence reduced scan time down to 1:17 with net acceleration 10.8 identifying the main arteries. In conclusion, CS+PI improves supra-aortic artery depiction and achieves higher acceleration compared to PI only.
