Clinical Application of FDG-PET Imaging for Three-Dimensional Myocardial Scar and Left Ventricular Anatomy During Ventricular Tachycardia Ablation

This review provides an overview of the role of cardiac positron emission tomography (PET) in assisting with the diagnosis of and facilitating the ablation procedure for ventricular tachycardia. It expands on the relative advantages and disadvantages of PET compared with other imaging modalities as well as the available evidence supporting its value in the assessment of viability for nontransmural myocardial infarction, hibernating myocardium, and assisting with the diagnosis and facilitating the ablation procedure for ventricular tachycardia patients. Furthermore, the fusion of multiple imaging modalities such as the combination of PET and x-ray CT for comprehensive scar characterization are briefly discussed.
