Semi-quantitative segmental perfusion scoring in myocardial perfusion SPECT: visual vs. automated analysis
Introduction: It is recommended that the physician apply at least a semi-quantitative segmental scoring system in myocardial perfusion SPECT. We aimed to assess the agreement between automated semi-quantitative analysis using QPS (quantitative Perfusion SPECT) software and visual approach for calculation of summed stress score (SSS), summed rest score (SRS) and summed difference score (SDS). ...

متن کاملMyocardial Perfusion: New Techniques
Coronary artery disease is the leading cause of death in the Western world. It is estimated that nearly 7 million people are living with coronary artery disease (CAD) in the United States and about half a million people die from it each year. The most common form of CAD leads to narrowing of the coronary arteries (stenosis) resulting in reduced blood flow and oxygen supplied to the heart muscle...
متن کاملRelationship of Regional Myocardial Perfusion to Segmental Wall Motion
coronary artery disease. We evaluated 270 segments in 54 patients, including 27 without evidence of myocardial infarction. Most normally perfused regions (125 of 140) contracted normally, whereas those with scintigraphic defects at rest were usually asynergic (42 of 46). Surprisingly, 57% (48 of 84) of regions with exercise-induced perfusion defects were also asynergic, including 48% (25 of 52)...
متن کاملCorrelation between echocardiographically demonstrated segmental dyskinesis and regional myocardial perfusion.
In order to evaluate the relationship between regional myocardial perfusion and segmental dyskinesis, 22 open chest dogs were studied using ultrasound to register cardiac wall motion and radioactive labeled microspheres to determine myocardial perfusion. In six dogs, motion and perfusion were correlated at two levels of partial circumflex coronary artery occlusion followed by complete occlusion...
