Background and Objective: The aim of this study was to demonstrate the utility of volume rendered multi-slice helical three-dimensional CT angiography in patients with cerebral aneurysm when compared with single slice CT angiography and formal digital subtraction angiography. Methods: A prototype Toshiba Aquilon multi-slice CT scanner was employed with the following scan conditions: voltage 135 kV;...
After introducing of Helical scanning CT (HCT) and 3D-CTA (three-dimensional CT angiography), various improvements to these methods have been made every year to achieve better imaging quality. The current resolution permits visualisation of the internal structure of tumors, although as yet insufficiently clearly. We suggest that these improvements can be more efficient than conventional cerebral aneurysms...
