The determination or assessment of myocardial viability has, over the past decade, captured the imagination and interest of many investigators in basic and clinical research using state-of-the-art technologies such as PET, SPECT, MRI and two-dimensional echocardiography (2-DE). The emphasis in these studies has been to determine the absolute and comparative accuracy of these techniques. There are recent studies addressing the evaluation of the effect of viability assessment on patient outcome. The use of biochemical agents and other imaging methods in viability assessment is complex with many unresolved issues to be considered in the design and implementation of clinical protocols and in routine patient care.
在过去十年中，心肌存活性的测定或评估吸引了众多基础研究和临床研究领域的研究者，他们运用正电子发射断层扫描（PET）、单光子发射计算机断层扫描（SPECT）、磁共振成像（MRI）以及二维超声心动图（2-DE）等先进技术展开研究。这些研究的重点在于确定这些技术的绝对准确性和相对准确性。近期有一些研究关注存活性评估对患者预后影响的评估。在临床方案的设计与实施以及常规患者护理中，使用生化制剂和其他成像方法进行存活性评估情况复杂，存在许多尚未解决的问题需要考虑。
