螺旋CT血管造影的临床应用

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ＣＴＡ２０例,肾脏ＣＴＡ４例。１０２例患中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。脑肿瘤疔见明显“肿瘤染色”。肺ＣＴＡ能显示１－４级肺动脉,肺癌供血动脉能清

The Clinical Value of CT-Angiography

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.
