Serial thallium-201 imaging after dipyridamole for coronary disease detection: quantitative analysis using myocardial clearance.

abstract：BACKGROUND:Previous studies have suggested that thrombolysis is used less often in blacks than in whites. However, whether the greater prevalence of contraindications or less specific electrocardiographic manifestations of myocardial infarction (MI) account for this difference is unclear. METHODS AND RESULTS:We studie...
