title: [Myocardial perfusion scintigraphy using 99mTC-tetrofosmin: a comparison with coronary angiography].
abstract: OBJECTIVE
  Coronary angiography is still the most reliable method for the detection of coronary artery disease. In this study we compared to this method the accuracy of 99mTc-Tetrofosmin myocardial SPECT.
  
  
  METHODS
  Fifty two patients (38 male and 14 female) were studied with stress-rest 99mTc-Tetrofosmin myocardial SPECT. Two independent observers evaluated the uptake of the radiotracer using a score from 0 to 4. All patients underwent coronary angiography and the results were compared to SPECT findings. We considered as hemodynamic significant any obstruction greater than 50% and as ischemic any myocardial region with radiotracer uptake less than 4 at stress.
  
  
  RESULTS
  There was good segmental correspondence between tetrofosmin scintigram and angiography. Sensitivity 72.2-91.1%, specificity 80.0-88.2%, ppv 76.4-88.5% and npv 83.3-85.7%, depending on the obstructed vessel.
  
  
  CONCLUSIONS
  99mTc-Tetrofosmin myocardial SPECT is a reliable alternative for the detection of CAD.
