Summary

The main purpose is to evaluate the accuracy of myocardial imaging obtained through integrated 18F-FDG PET/MR in detecting viable myocardium. The secondary objective is to evaluate whether myocardial imaging obtained through integrated 18F-FDG PET/MR can replace 18F-FDG PET combined with 99mTc MIBI SPECT/CT gated myocardial perfusion imaging.

Detailed description

A comprehensive evaluation of the degree of coronary artery stenosis, myocardial ischemia range, and survival status are required before surgery, which can help predict postoperative efficacy and select the best treatment plan. Only when the heart muscle is alive, can the myocardial blood flow return to normal after revascularization surgery, improving left ventricular ejection fraction (LVEF) and long-term survival rate of patients. Performing coronary artery bypass grafting(CABG) on patients with lack of myocardial activity not only cannot benefit them, but also increases the risk of surgery. At present, the combination of 18F-flurodeoxyglucose(FDG) Positron Emission Tomography/ Computed Tomography(PET/CT) imaging and myocardial perfusion imaging is the most commonly used method in clinical practice to determine myocardial activity based on the matching of metabolism and blood flow. In recent years, the value of Cardiovascular Magnetic Resonance(CMR) in ischemic diagnosis and myocardial infarction assessment has been widely clinically validated, and many techniques in CMR have been included in clinical guidelines. Late Gadolinium Enhancement(LGE) imaging is the most accurate non-invasive technique for evaluating myocardial scars currently. Integrated Positron Emission Tomography/Magnetic Resonance imaging(PET/MR) can simultaneously evaluate myocardial perfusion, metabolism, vitality, and function, which has certain value for the diagnosis of myocardial ischemia and clinical prognosis of revascularization surgery.
