Conventional angiography is the gold standard in evaluating for cerebrovascular disease and for providing less-invasive endovascular interventions. This modality can be performed to clarify equivocal findings or to confirm and treat disease seen on MRA, CTA, transcranial Doppler, or neck ultrasonograms. However, Zhu et al found that in patients with spontaneous intracranial hemorrhage, angiographic yield was significantly lower in patients older than 45 years and those who had preexisting hypertension.
