Analysis of baseline and cardiac function factors affecting the image quality of contrast-free 3.0T MR coronary angiography

Magnetic resonance coronary angiography (MRCA) imaging technology is still somewhat sophisticated, with numerous elements influencing image quality. This study found that for subjects with high BMI, high heart rate, and high systolic blood pressure, further optimization of imaging sequences and parameters is needed to explore individualized coronary MR imaging protocols.
