Comparison of Magnetic Resonance Coronary Angiography (MRCA) With Coronary Computed Tomography Angiography (CTA)

Magnetic resonance coronary angiography (MRCA) has its advantage in its ability to assess the coronary artery morphology without radiation or contrast media. The clinical application of MRCA is still challenging mainly because of technical limitations such as: its time-consuming image acquisition, inconsistent image quality, and low spatial resolution. Optimization of …
