Dynamic Tracking During Intracoronary Injection of 18F-FDG-Labeled Progenitor Cell Therapy for Acute Myocardial Infarction

Abstract

Dynamic tracking during intracoronary injection of (18)F-FDG-labeled CPC is feasible and demonstrates significant cell washout from the myocardium immediately after balloon deflation. High-concentration, single-bolus therapy may be as effective as balloon-occlusion delivery. This tracking technique should facilitate development of improved delivery strategies for cardiac cell therapy.
