Pathophysiologic considerations and clinicopathological correlates of technetium-99m stannous pyrophosphate myocardial scintigraphy.

摘要: 99mTc-PYP myocardial scintigrams represent a means to detect and localize acute necrosis. These are expected be abnormal with infarcts of at least 3 grams in weight if serial imaging is utilized proper attention technique provided. Any etiology necrosis may produce the damage relatively localized includes tissue. It possible accurately size anterior anterolateral transmural using area or 2 dimensional measurements. Further development cameras computer techniques allowing three reconstruction this similar allow precise quantitation other types infarcts. The "doughnut" "persistently abnormal" appear have anatomic prognostic significance subsets patients studied, but larger numbers individuals need evaluated before final conclusions regarding their ultimate can reached.
