核素心肌灌注显像在冠心病诊断中的价值

核素心肌灌注显像（MPI）作为一种无创性检查，它的独特之处是以功能显像为主，而不只是单纯的解剖形态显像，它能客观、准确地评价冠状动脉病变引起的心肌血流灌注、心肌细胞功能与心室功能异常等病理生理的改变。本文对MPI在冠心病的诊断、治疗决策、疗效评估以及预后判断等方面及相关进展做一综述。

Diagnostic and treatment value of radionuclide myocardial perfusion imaging in coronary heart disease

As a non-invasive examination measure, radionuclide myocardial perfusion imaging （MPI） is of its own uniqueness in functional imaging rather than simply anatomic imaging. It can objectively and accurately assess pathophysiological changes caused by coronary artery lesions, including myocardial perfusion, myocardial cells function and ventricular dysfunction. In this paper, we reviewed the application of radionuclide MPI in the diagnosis, treatment decisions, efficacy prediction and prognosis judgment of coronary heart disease.
