Abstract:
Objective To explore the feasibility of coronary magnetic resonance angiography(CMRA) with a T2-prepared turbo field echo(T2-TFE) sequence at 3.0T MR scanner.Methods 33 objects underwent CMRA at 3.0T MR imaging unit.The CMRA was performed with a 3D T2-TFE sequence.Electrocardiographically gating combined with real-time respiratory navigator gating and tracking was used to suppress the cardiac motion and correct for respiratory-induced coronary artery motion.The original images were reconstructed with MIP and Soap Bubble software.The quality of CMRA was evaluated and the lengths of the main coronary arterial branches were measured.Results 115 of 128 coronary arteries were scored higher than 3 with the standard of image quality.The lengths of LM,LAD,LCX and RCA were(12.0?3.8) mm,(79.4?18.9) mm,(60.0?12.7) mm and(110.7?27.2) mm,respectively.Conclusion CMRA with T2-TFE sequence is feasible at 3.0T.
