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...

متن کاملAutomated quantification of myocardial perfusion SPECT using simplified normal limits.
BACKGROUND To simplify development of normal limits for myocardial perfusion SPECT (MPS), we implemented a quantification scheme in which normal limits are derived without visual scoring of abnormal scans or optimization of regional thresholds. METHODS AND RESULTS Normal limits were derived from same-day TI-201 rest/Tc-99m-sestamibi stress scans of male (n = 40) and female (n = 40) low-likeli...

متن کاملMicrovascular control of myocardial perfusion
Myocardial perfusion is closely linked to oxygen demand, which is met by regulation of the resistance to flow in small arteries and arterioles via smooth muscle tone. Adjustment of smooth muscle tone occurs by modulation of the cytosolic calcium concentration, via influx of calcium across the cell membrane through a variety of calcium channels and release of calcium from the sarcoplasmic reticu...
