Abstract
Myocardial SPET has emerged as an important noninvasive diagnostic and prognostic method for assessment of patients with suspected CAD. Respiratory motion is a potential cause of motion artefact and reduced image quality in ECG-gated SPET (GSPET). In this investigation, we studied the effects of respiratory motion on GSPET concerning regional myocardial perfusion and function by simulation study. The NCAT phantom allowed simulation of respiratory motion with different amplitude for diaphragm (0 to 7 cm with increment of 1 cm) and anterior-posterior extension (from 0 to 1.7 cm). SimSET was used to generate simulated projection data. Emission data were generated over one respiratory cycle, divided into 80 phases. Data were reconstructed using the ordered subsets exceptional maximization (OSEM) method without attenuation and scatter correction. Quantitative analysis of regional myocardial perfusion and function were performed by Emory cardiac toolbox software.
