Other imaging studies for subarachnoid<unk>  include digital-subtraction cerebral angiography and CT/MR angiography. Once the diagnosis of subarachnoid<unk>  is confirmed, the next question is about its origin. CT angiography (using radiocontrast) to identify aneurysms is generally the first step, as invasive angiography (injecting radiocontrast through a catheter advanced to the brain arteries) has a small rate of complications but is useful if there are plans to obliterate the source of bleeding, such as an aneurysm, at the same time.
