Abstract
PURPOSE: We compared three-dimensional image (3-D-CT) angiography with
conventional angiography to determine the clinical usefulness of this
technique. MATERIALS AND METHODS: We studied 15 patients with cerebral
aneurysms using dynamic CT with intravenous injection of contrast material
and reconstructed 3-D-CT angiography. RESULTS: 3-D-CT angiography could be
performed in conjunction with standard axial high-resolution CT without
any additional scanning time and within 10-30 minutes for the overall
study. All aneurysms were clearly visualized by 3-D-CT angiography.
3-D-reconstruction was very helpful in demonstrating the neck, shape, and
direction of aneurysms, and adjacent vascular and bony structures. One
small aneurysm that was difficult to detect on axial images was clearly
visualized on 3-D-reconstruction. CONCLUSION: 3-D-CT angiography of
cerebral aneurysms could be performed routinely and was helpful in
demonstrating the complex anatomy of cerebral aneurysms and surrounding
structures. This technique will be of value in surgical planning.
