Influence of reconstruction algorithms on image quality in SPECT myocardial perfusion imaging

Summary Introduction We investigated if image‐ and diagnostic quality in SPECT MPI could be maintained despite a reduced acquisition time adding Depth Dependent Resolution Recovery (DDRR) for image reconstruction. Images were compared with filtered back projection (FBP) and iterative reconstruction...
