  • Abstract
  • Look Inside

Transparent imaging with volume rendering of CT angiography (CTA) was used to delineate cerebralaneurysms. Five unruptured cerebral aneurysms discovered incidentally on MR angiography were deline-ated as transparent CTA images and compared with routine three-dimensional CTA images. Reconstruct-ing the volume data sets by adjusting the opacity level and range of CT values allowed transparentvisualization 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 thebony structure.
