多层螺旋CT对冠状动脉血管的评价

多层螺旋CT作为一种安全、非侵入性的冠状动脉粥样硬化病变检查方法已为人们接受。其临床应用有着很大的潜力,它不仅可以发现显著的冠状动脉狭窄,还可以检出尚未引起狭窄的钙化及非钙化(脂质及纤维)斑块,随着技术进步,多层螺旋CT有可能取代冠状动脉造影完成对早期亚临床冠状动脉疾病的筛查。冠状动脉钙化积分对冠状动脉的评价要优于传统风险因素,它对总的冠状动脉的斑块负荷的评估可以提供更有力的预测。它还可用于其它冠状动脉疾病的评价。现主要介绍多层螺旋CT冠状动脉血管成像的临床应用现状。

Usefulness of Multi-slice Computed Tomographic Coronary Angiography in Assessment of Coronary Artery

Multislice computed tomography (MSCT) coronary angiography is a safe,noninvasive,patient-friendly diagnostic modality to detect the presence of coronary atherosclerosis. The clinical potential of the cardiac spiral CT is large because it can detect not only the significant coronary stenoses,but also the presence of nonobstructive calcific and noncalcific (lipid or fibrous) plaques. With advanced technology,MSCT might replace invasive diagnostic coronary angiography to detect early subclinical coronary arter...
