Bone subtraction CT angiography for the detection of intracranial aneurysms.
The aim of the study was to retrospectively analyse the accuracy of CT angiography (CTA) of the Circle of Willis and a prototype bone subtraction CT angiogram (BSCTA) compared with digital subtraction angiography (DSA) in the detection of intracranial aneurysms. ⋯ In this study there was no significant difference between the diagnostic ability of BSCTA compared with CTA. Importantly, both CTA and BSCTA had high sensitivities and specificities compared to DSA.
