Noninvasive imaging with radioactive tracers has become widely used since its introduction in the early 1970s. Improvements continue to be made in the techniques and the clinical applications. Much of the information provided by these techniques is new. The first transit studies are used mainly in the evaluation of pulmonary transit time, detection of intracardiac shunting, evaluation of right ventricular function, measurement of ejection fraction and detection of wall motion abnormalities at rest and after exercise. The gated blood pool study is found to be most useful in assessment of global left ventricular function, regional wall motion, valve regurgitation and right ventricular function. The techniques of nuclear cardiac imaging are noninvasive, simple, successfully performed in almost 100 percent of cases. They are easy to interpret, able to be quantified and able to be almost totally automated. Their use is likely to become more widespread in the future.
自20世纪70年代初放射性示踪剂的无创成像技术问世以来，它已得到广泛应用。该技术及其临床应用一直在不断改进。这些技术所提供的许多信息都是全新的。首次通过研究主要用于评估肺循环时间、检测心内分流、评估右心室功能、测量射血分数以及检测静息和运动后的壁运动异常。门控血池研究在评估左心室整体功能、局部壁运动、瓣膜反流和右心室功能方面最为有用。核心脏成像技术是无创的、简单的，几乎在100%的病例中都能成功进行。它们易于解读，能够进行量化，并且几乎可以完全自动化。未来它们的应用可能会更加广泛。
