This review is concerned with qualitative and quantitative sectorial 201Tl-redistribution analysis of exercise myocardial scintigraphy (EMS). In 3092 cases the sensitivity (specificity) was on average 83 (90) %, the average CAD prevalence being 71%. Sensitivity (Se) for EMS (ExECG) increased from 73 (43) % in single vessel disease through 83 (69) % in double vessel to 90 (77) % in triple vessel disease (n = 879); average Se was 77% for LAD-, 79% for RCA- and 65% for LCX-stenosis. Se for detection of the real extension of CAD conversely decreased from 59% in SVD through 41% in DVD down to 33% in TVD. Clinical recommendations for EMS and rest scans are outlined in CAD (atypical angina, follow-up after bypass-surgery, percutaneous transluminal angioplasty), in non-coronary artery disease (non-ischemic cardiomyopathies, right ventricular hypertrophy) and in pediatric cardiology.
