The Number of Frames on ECG-Gated ¹⁸F-FDG Small Animal PET Has a Significant Impact on LV Systolic and Diastolic Functional Parameters

Figure 1

Dynamic ¹⁸F-FDG PET images (a) and time activity curve (b) after tracer administration via the tail vein under hyperinsulinemic-euglycemic clamp conditions. Frame data from 15-35 min (stable left ventricular delineation phase) were used for subsequent ECG-gating functional analysis. Dynamic PET imaging revealed a time course with rapid clearance of administered ¹⁸F-FDG from the blood pool (<10 min), followed by stable tracer accumulation in the myocardium (>10 min). SA: short axis; HLA: horizontal long axis.
