[Transparent imaging of CT angiography for the delineation of cerebral aneurysms].
Transparent imaging with volume rendering of CT angiography (CTA) was used to delineate cerebral aneurysms. Five unruptured cerebral aneurysms discovered incidentally on MR angiography were delineated as transparent CTA images and compared with routine three-dimensional CTA images. Reconstructing the volume data sets by adjusting the opacity level and range of CT values allowed transparent visualization of the aneurysm with its related vessels through the bony structures of the cranial base. Transparent imaging of CTA may be a useful adjunct for the evaluation of an aneurysm adjacent to the bony structure.
