Incidental Findings on Myocardial Perfusion SPECT Images

Myocardial perfusion SPECT: Perfusion quantification

Different software tools for quantification of myocardial perfusion SPECT (MPS) studies are routinely used. Several perfusion parameters can be computed automatically.  Interpretation of the MPS should start with visual inspection of the rotating planar images, visual analysis of reconstructed SPECT slices and then quantitative analysis to confirm the visual impression. Quantification should be...

False-positive findings on myocardial perfusion SPECT.

TO THE EDITOR: Recently, there have been 3 articles (1–3) published in The Journal of Nuclear Medicine attempting to define various artifactual sources that contribute to the unacceptably high rate of myocardial perfusion SPECT (MPS) studies with falsepositive findings. Each article suggests a different protocol modification intended to reduce the incidence of false-positive MPS findings. The f...

Dipyridamole stress and rest gated 99mTc-sestamibi myocardial perfusion SPECT: left ventricular function indices and myocardial perfusion findings

  Introduction: We investigated the difference in left ventricular ejection fraction (LVEF) and end-systolic volume(ESV) measured by gated myocardial perfusion SPECT (GSPECT) in the post-dipyridamole stress and rest periods, and compared the results with the perfusion patterns found in the conventional non-gated tomograms. Methods: 297 consecutive patients were studie...
