Methods: Axial source images were obtained by helical CT scanning and reconstruction of 3D-CTA images was done by volume rendering technique in conjunction with multiplanar reformation. Results: In the past one year, there were 10 patients diagnosed as having multiple intracranial a-neurysms by 3D-CTA and altogether 24 aneurysms were visualized, including 10 small aneurysms (≤ 5mm. Three-dimensional CT angiography with volume rendering demonstrated aneurysms very well and provided useful information concerning the site, shape, size and spatial relationship with the surrounding vessels and bone anatomy. Conclusion: Three-dimensional CT angiography with volume rendering is a quick, reliable, and relatively noninvasive method for diagnosing multiple intracranial aneurysms. It delineates detailed aneurysmal morphology, and provides useful information for planning microsurgical approaches.展开更多
