In the coronary artery disease group, 82 patients had positive thallium scan and in normal coronary group, 23 patients had positive scan.Result- The calculated sensitivity of the test for detecting CAD was about 85% and the specificity was about 64%. Positive and negative predictive values were about 75% and 78%, respectively. The sensitivity and specificity of the test for detecting LAD, RCA and LCX disease was 89% and 61%, 80% and 59% and 54% and 60%, respectively.Conclusion- this study reveals that although dipyridamole thallium scan is sensitive for detection of myocardial ischemia, the specificity of the test is not remarkable.}, keywords = {DIPYRIDAMOLE THALLIUM SCANS,myocardial ischemia,Coronary Artery Disease}, url = {http://journal.iha.org.ir/article_84180.html}, eprint = {http://journal.iha.org.ir/article_84180_7a6800400f395ab4c303a5284b356e1a.pdf} }
