心脏病是危害人民健康的主要疾病之一,对心功能都有不同程度的损害。监测这些改变,及时了解患者的病情,对治疗决策、疗效和预后的判断均十分重要。核素显像测定心功能是一种成熟可靠的无创性方法,能够提供心室大小、心肌灌注、心脏收缩和舒张功能等多方面的信息,有助于对心功能异常做出早期诊断和治疗。随着正电子发射计算机体层显像技术(PET)和高分辨力PET/CT在临床应用逐渐增多,核素显像测定心功能的结果将更为准确、可靠。 Heart disease is one of the major diseases endangering the health of the people, and has various degrees of damage to heart function. Monitoring these changes to keep abreast of the patient’s condition is crucial to the decision-making of treatment, the efficacy and prognosis. Radionuclide imaging is a proven and noninvasive method of determining cardiac function and provides information on ventricular size, myocardial perfusion, systolic and diastolic function, and early diagnosis and treatment of cardiac dysfunction. With the increasing use of positron emission tomography (PET) and high-resolution PET / CT in clinical practice, the results of radionuclide imaging in determining cardiac function will be more accurate and reliable.
