Multidetector CT Angiography Promising for Brain Aneurysm

DUISBURG, Germany, July 31 -- Multidetector CT angiography can diagnose and assess intracranial aneurysms with equivalent accuracy to digital subtraction angiography, investigators here reported.

Compared with DSA, the investigators found that multidetector CTA had a sensitivity of 98% and a specificity of 100% for detecting brain aneurysms, according to an article in the August issue of Radiology. In addition, multidetector CTA predicted the feasibility of endovascular treatment with 94% sensitivity and 92% specificity.

We conclude that multidetector CT angiography… can be used as the first step in the diagnostic workup of patients with subarachnoid hemorrhage," said Karsten Papke, M.D., of the Duisburg Clinic, and colleagues.
