Comparison among Reconstruction Algorithms for Quantitative Analysis of ¹¹C-Acetate Cardiac PET Imaging

Figure 1

PET images reconstructed by TOF protocol: a transversal slice (a), a coronal slice along the higher dashed line (b), a coronal slice along the lower dashed line (c). The iterative reconstruction was performed with 10 iterations and 10 subsets, and a 5 mm (FWHM) Gaussian filter was applied (axial and transaxial) after reconstruction. The scan started 450 seconds after ¹¹C-acetate injection with the scan duration of 30 seconds. The four myocardial ROIs with 5 mm in diameter were evenly distributed along the myocardial wall (ROI –) and the two blood-pool ROIs with 10 mm in diameter were located in the center of the left ventricle (ROI ) and right ventricle (ROI ).
