目前,冠心病的影像学检查主要有两种方法,X线冠脉造影(CAG)和CT冠脉成像(CTA)。CAG是冠心病诊断的“金标准”得到了大家公认,但它作为一种有创的检查手段而限制了在临床中的普及。应用64排容积CT进行冠脉血管成像具有无创、快捷、风险小、价格相对低廉的优点,不仅能获得优良的冠状动脉CT图像,而且可以从解剖上发现冠脉肌桥等血管变异,对冠脉病变具有较高的敏感性和特异性,现已得到临床实践的广泛验证,成为冠心病诊断的首选检查。1对象与方法1.1对象选取2009年1月至2011年6月在我院CTA检
At present, there are mainly two kinds of imaging examination of coronary heart disease, X-ray coronary angiography (CAG) and CT coronary angiography (CTA). CAG is a gold standard in the diagnosis of coronary heart disease has been recognized, but it limits invasive clinical as an invasive means of examination. Application of 64-row volumetric CT coronary angiography has the advantages of non-invasive, fast, low risk, relatively inexpensive, not only can obtain excellent CT images of coronary arteries, but also can be found from the anatomy of vascular variability such as coronary artery bridge, the crown Pulse disease has a high sensitivity and specificity, has been widely validated clinical practice, a diagnosis of coronary heart disease as the preferred examination. 1 objects and methods 1.1 object selection January 2009 to June 2011 in our hospital CTA seized
