After performing stress myocardial perfusion scintigraphy in patients at low risk for coronary artery disease, does addition of rest diagnostic imaging change the diagnosis?

1866 Objectives To estimate the proportion of subjects (without a history of coronary artery disease, without typical chest pain, and Methods In 171 retrospective chart reviews, 50 subjects met inclusion criteria. Subsequently, pharmaceutical induced Tc-99m MPS (Myocardial Perfusion Scintigraphy) was performed. 4 ABNM certified physicians were randomly assigned 12-13 patients. They first read the pharmaceutical induced stress only Tc-99m MPS images for their set of patients. Then they read the rest+stress images, for the same patients. Images were in random order without identifiers. Results were classified as Normal, Equivocal or Abnormal. For all readers, 2 normal, 2 equivocal and 2 abnormal diagnostic images were inserted into the rests+stress set to prevent recollection bias. Results Gender was associated with a significant change in results (p Conclusions In our study, 95.2% (95% CI, 76.2-99.9%) of
