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

Example images of the edge detection of left ventricular wall and 3D images of the ventricular borders (a). Time-volume curves (b) and corresponding time-filling curve of the same animal with different numbers of gates per cardiac cycle. The smoothening of both curves due to the increasing number of volume values with increasing gate number is demonstrated as well as the calculation of the LV volumes and the PFR. EDV: end-diastolic volume; ESV: end-systolic volume; SV: stroke volume; EF: ejection fraction; PFR: peak filling rate.
