Cardiovascular diseases (CVDs) are the main cause of mortality worldwide, with coronary artery disease (CAD) noted as one of the major causes of CVD. An early and accurate diagnosis is important for improved outcomes in CAD patients. Invasive coronary angiography and coronary computed tomography angiography are accurate diagnostic tools for CAD. However, these examination methods possess limitations, including invasiveness and use of ionizing radiation, which limit their application in certain population groups. Meanwhile, coronary magnetic resonance angiography (CMRA) represents a noninvasive method that provides high-resolution coronary artery images without ionizing radiation and contrast agents. Nonetheless, the quality of CMRA images depends on numerous physiological and technical factors. This review analyzes the main factors that affect CMRA image quality and provides theoretical and technical insights for better clinical application of CMRA in CAD diagnoses.
