摘要
近年来，双源双能量CT心肌灌注成像在临床中的应用及研究逐渐增多，能够反映心肌微循环状况，定性及定量地评价心肌血流状态，检测心肌微循环及心肌活性，并且可以在评估冠状动脉的同时评估由于心肌缺血导致的心肌受损情况。其诊断心肌损伤的灵敏度、特异度、阴性预测值和阳性预测值与组织病理学检查的一致性好。相对于其他检查技术，双能量心肌灌注成像能便捷地提供更丰富的临床信息。笔者对双源双能量CT心肌灌注成像的研究进展进行综述。
In recent years, dual-energy myocardial perfusion imaging via dual-source CT has been extensively used in clinical diagnoses and research. This technique can reflect the condition of myocardial microcirculation blood flow, qualitatively and quantitatively evaluate myocardial blood flow, identify myocardial microcirculation and myocardial viability, assess myocardial damage caused by myocardial ischemia, and assess the coronary artery. The sensitivity, specificity, negative predictive value, and positive predictive value of the diagnosis of myocardial damage demonstrated good consistency with pathologic tissue examination. Compared with other techniques, dual-energy myocardial perfusion imaging provides more detailed clinical information. This paper reviews the progress of dual-energy myocardial perfusion imaging via dual-source CT in clinical applications.
