AB  - BACKGROUND: We developed a data-driven respiratory motion (RM) correction method 
      (REGAT program) for multiple-pinhole detector CZT SPECT. We verified its clinical 
      feasibility with myocardial perfusion imaging (MPI) and studied its impact on 
      image characteristics. METHODS: This retrospective study included 18 patients 
      having stress/rest (99m)Tc-Tetrofosmin MPI SPECT. List mode was acquired on CZT 
      SPECT and processed with REGAT. REGAT generates reconstructed RM-gated volumes 
      that are summed either without realignment (NR-SPECT) or after realignment 
      (R-SPECT). For both stress and rest, we calculated the maximal RM in the 3 axis, 
      and image characteristics of both R-SPECT and NR-SPECT: minimum left ventricular 
      (LV) cavity counts (LV-Min), maximum LV myocardial counts (LV-Max), LV contrast, 
      and FWHM of both anterior (FWHM-ant) and inferior (FWHM-inf) LV myocardial walls. 
      RESULTS: At both stress and rest, cranio-caudal motion was the dominant axial 
      movement and REGAT had a positive impact on image characteristics as reflected by 
      variations between R-SPECT and NR-SPECT in LV-Min, LV-Max, FWHM-ant, FWHM-inf, 
      and contrast. These latter were well correlated to the amplitude of cranio-caudal 
      motion at both stress and rest. CONCLUSIONS: Data-driven RM correction of MPI 
      acquired with CZT SPECT is clinically feasible and easily applicable. It presents 
      interesting impact on image characteristics.
