Abstract: The ¹⁸F-FDG PET/CT myocardial metabolism imaging is currently recognized as the "gold standard" for monitoring patient myocardial survival and plays a guiding role in the treatment of coronary heart disease and the prognosis evaluation of vascular recanalization. Ensuring qualified image quality is the key in achieving this role. However, the myocardial metabolism imaging quality of ¹⁸F-FDG PET/CT is affected by many factors, such as diet before examination, fasting time, long-term drug use, daily blood glucose level examination, blood glucose regulation methods and the timing of tracer injection. To this end, the author intends to review the research status and the latest progress of the factors affecting the quality of myocardial metabolism imaging with the ¹⁸F-FDG PET/CT.
