摘要
目的：评价CT血管造影临床应用价值。材料和方法：CT血管造影102例，其中脑CTA62例，颈部CTA4例，肺CTA10例，肝脏CTA20例，脾脏CTA2例，肾脏CTA4例。102例患者中51例还进行了DSA对照检查。结果：62例脑CTA均能显示1～5级脑动脉结构。脑动脉瘤及脑动静脉畸形均经CTA检出，诊断结果与DSA一致。脑肿瘤可见明显“肿瘤染色”。肺CTA能显示1～4级肺动脉，肺癌供血动脉能清楚显示。肝脏CTA对肝癌和肝血管瘤能予以区分。肾动脉狭窄可经CTA明确诊断。结论：CTA为非损伤性血管检查方法，安全简便，阳性检出率高，在临床应用上具有许多优点，在诊断方面可作为常规方法使用。
To evaluate clinical value of CT angiography, CTA. Materials and Methods: In series of102 cases with CTA,62 cases of the brain, 20 cases of the liver, 10 cases of the lung, 4 cases of the cer-vical,4 cases of the kidney, 2 cases of the spleen. As comparision , 51 cases were checked by DSA. Re-sults: all the images of 62 cases with cerebral CTA demonstraed 1~5 grades branches of cerebral artery.Among them, 22 cases of the aneunysms nd 6 cases of the arteriovenous malformations were all found byCTA and corresponded with DSA. The cerebral tumors appeared 'tumor stain' obviously. The images of pulmonary CTA showed 1 ~ 4 grades branches of pulmonary artery. The supplying artery of the lung tumorcould be showed clearly. Hepatic cancer was differentiated from hepatic hemangioma with CTA. The renalartery stenosis could be diagnosed by CTA. Conclusion: CTA is a nonivasive angiographic methed that issafty and convenient. It has many advantages in clinical application and can be used as routine method indiagnosis.
