The diagnostic possibilities of myocardial scintigraphy in cardiology are discussed. As an invasive technique the perfusion imaging is described. The valuation of the doubleisotope-scintigraphy for better diagnostic examination during coronary arteriography is accentuated. The 201-Thallium-scintigraphy as a non invasive method is debated. The diagnostic value of the 201-Thallium stress scintigraphy is shown. The similarity of ergometric and pharmacologic provocation with Dipyridamol is represented. In the following the reliability and the specificity of the infarct scintigraphy with 99m-Technetium-pyrophosphate as "hot-spot-technique" is discussed. The follow-up scintigraphy allows to draw prognostic inferences about the further course of a myocardial infarction. The scintigraphic findings were correlated to haemodynamic measurements. Scintigraphic examinations in patients with stable angina pectoris without infarction revealed correlations between the uptake of the tracer in the myocardium and a disturbed left ventricular function. A chronic deficiency in the blood supply of the myocardium is discussed as the cause of the tracer uptake.
本文讨论了心肌闪烁造影在心脏病学中的诊断可能性。文中描述了作为一种侵入性技术的灌注成像。着重强调了双同位素闪烁造影在冠状动脉造影期间进行更好诊断检查的价值。对作为非侵入性方法的铊-201闪烁造影进行了讨论。展示了铊-201负荷闪烁造影的诊断价值。阐述了运动试验和用双嘧达莫进行药物激发试验的相似性。接下来讨论了以99m-锝焦磷酸盐作为“热点技术”的梗死闪烁造影的可靠性和特异性。随访闪烁造影有助于对心肌梗死的进一步病程作出预后推断。闪烁造影结果与血流动力学测量结果相关。对无梗死的稳定型心绞痛患者进行的闪烁造影检查显示，心肌中示踪剂摄取与左心室功能紊乱之间存在相关性。文中讨论了心肌长期供血不足作为示踪剂摄取原因的情况。
