چکیده مقاله:

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 used routinely as complementary to visual analysis. Advantages of quantification are: greater confidence in interpretation, better reproducibility, diagnostic accuracy and measuring the degree of abnormality even subtle changes for serial comparisons. In this review, we look at the common features of such quantitative tools: 17-segment scoring system, polar maps including: raw, severity and extent polar maps, lung-to-heart ratio, transient ischemic dilation ratio, total perfusion deficit and spherecity index.

Evaluation of myocardial perfusion and function after kidney transplantation by Gated SPECT myocardial perfusion scintigraphy

Introduction: The aim of this study was to evaluate the effect of successful kidney transplantation (KT) on myocardial perfusion and left ventricular function by both qualitative (visual) interpretation and semiquantitative parameters, using myocardial perfusion scintigraphy with gated-single photon emission computed tomography (gated-SPECT) in patients suffering from end-stage renal disease. ...

Filter selection for 99mTc-Sestamibi myocardial perfusion SPECT imaging [Persian]

Myocardial perfusion SPECT imaging with Tc99m-sestamibi is the most accurate non-invasive means of detecting coronary artery disease and assessing the severity of perfusion abnormalities in the patients with coronary stenosis. Though simple and straight forward the results produced by the technique is very much affected by the details being used. One of the main problems with the test, wh...
