Both technical and clinical implications of three-dimensional computed tomographic angiography in the evaluation of intracranial circulation, and in particular cerebral aneurysms, are presented. Three-dimensional computed tomographic angiography allows excellent visualization of the aneurysm, its neck, and its relationship with the parent artery and important adjacent bony structures. This technique has a major role in the evaluation of difficult aneurysms. In addition, advantages and disadvantages are discussed in comparison with more conventional techniques such as magnetic resonance imaging, magnetic resonance angiography, and digital subtraction angiography. Three-dimensional computed tomographic angiography will continue to develop with the advent of more rapid computed tomography scanners, playing a key role in the investigation and screening of patients with a family history of cerebral aneurysms.
本文介绍了三维计算机断层血管造影术在评估颅内循环，尤其是脑动脉瘤方面的技术和临床意义。三维计算机断层血管造影术能够出色地显示动脉瘤、其颈部以及它与供血动脉和重要相邻骨性结构的关系。该技术在评估复杂动脉瘤方面具有重要作用。此外，还与磁共振成像、磁共振血管造影和数字减影血管造影等更传统的技术进行了比较，讨论了其优缺点。随着更快的计算机断层扫描仪的出现，三维计算机断层血管造影术将不断发展，在对有脑动脉瘤家族史患者的检查和筛查中发挥关键作用。
