Which is the gold standard method of cerebral angiography?
Digital subtraction angiography (DSA) is generally used as the gold standard in detection of intracranial aneurysms.
How accurate is the cerebral angiogram?
Using DSA as the gold standard, CTA detected ≥50% stenosis with a sensitivity of 97.1% (95% CI: 85 to 99.9%), a specificity of 99.5% (95% CI: 98.4 to 99.9%), and a NPV of 99.8% (95% CI: 98.7% to 100%; Table 2). CTA indicates CT angiography; DSA, digital subtraction angiography. Data presented are vessel segments.
