[3-dimension computed tomography angiography and digital subtraction angiography in diagnosis of intracranial aneurysm: a comparative study].

Objective: To compare the appliance values off 3-dimension computed tomography (CTA) and digital subtraction angiography (DSA) in diagnosis of intracranial aneurysm (ICA).

Methods: Eighty-six with subarachnoid hemorrhage underwent 2-D DSA, and 3-DCTA and 3-D DSA, both including maximum intensity projection (MIP) and multiple planner reconstruction (MPR), volume rending (VR). The accuracy, misdiagnosis rate, and missed diagnosis rate of these 3 techniques were compared.
