Development of ¹⁸F-FDG PET myocardial metabolic imaging in the diagnosis of myocardial survival

Severe coronary artery disease is the cause of left ventricular dysfunction, and the treatment for this disease is not effective. Many coronary angiographies showed that severe coronary stenosis did not significantly improve heart function after treatment, except for a few patients. Therefore, effective assessment of the myocardial viability status for the coronary revascularization choice and efficacy has significant predictive value. Nuclide myocardial imaging as a noninvasive examination plays an important role in the diagnosis of coronary heart disease, risk stratification, ischemia assessment, prognosis, and so on. ¹⁸F-FDG PET imaging of myocardial metabolism can accurately assess the status and proportion of myocardial viability and possesses an important role in the outcome of coronary heart disease and the effect of treatment.
