The latest versions of spiral CT scanners have provided the radiologist with unparalleled capabilities for vascular imaging. Computed Tomographic Angiography (CTA) has the potential of revolutionizing vascular imaging and with evolving improvements may replace conventional angiography in the near future
To report our initial experience with CTA in Nigeria; highlighting its usefulness as a non invasive modality and its clinical applications in diagnosis of vascular abnormalities of various parts of the body.
We reviewed 62 patients who had CTA between December 2003 and September 2005.. The studies were performed using a spiral technique with GE CT/e single-slice scanner (General Electric Medical Systems) having a gantry rotation period of one second. Details of techniques of data acquisition, methods of 3-D reconstruction and clinical applications are discussed.
Vascular abnormalities were demonstrated in 26 (42%) patients including 5 cranial arteriovenous malformations (AVMs), 3 intracranial aneurysms, 1 spinal AVM, 3 aortic aneurysms, 5 carotid artery stenosis, and 2 traumatic peripheral aneurysms.
Correlations between CTA and surgical findings were good. CT angiography has enhanced our practice of vascular radiology in Ibadan as it has done in the west and other parts of the world.
最新版本的螺旋CT扫描仪为放射科医生提供了无与伦比的血管成像能力。计算机断层血管造影（CTA）有可能彻底改变血管成像技术，并且随着不断改进，在不久的将来可能会取代传统血管造影。
报告我们在尼日利亚进行CTA的初步经验；强调其作为一种非侵入性检查方法的实用性及其在诊断身体各部位血管异常中的临床应用。
我们回顾了2003年12月至2005年9月期间接受CTA检查的62例患者。研究采用螺旋技术，使用GE CT/e单排扫描仪（通用电气医疗系统公司），机架旋转周期为1秒。讨论了数据采集技术、三维重建方法及临床应用的细节。
26例（42%）患者显示有血管异常，包括5例颅内动静脉畸形（AVM）、3例颅内动脉瘤、1例脊髓AVM、3例主动脉瘤、5例颈动脉狭窄和2例创伤性外周动脉瘤。
CTA与手术结果的相关性良好。CT血管造影增强了我们在伊巴丹的血管放射学实践，就像它在西方和世界其他地区所做的那样。
