【摘要】Objective To compare the values of 256-slice CT angiography (3D-CTA) and 3D digital subtraction angiography (3D-DSA) in the diagnosis of intracranial aneurysms. Methods Forty-six patients whose clinical manifestations were highly suspected as subarachnoid hemorrhage (SAH) or suspected as aneurysms on magnetic resonance angiography (MRA) were analyzed retrospectively. Both head 3D-CTA and 3D-DSA were performed in all the patients. Two radiologists independently interpreted the 3D-DSA images of all the patients using double blind method, and the 3D-DSA was interpreted and judged by a neurologist and a radiologist. With the number of aneurysms detected by 3D-DSA as the standard, the sensitivity and specificity of 3D-CTA as well as the consistency of the number of aneurysms detected between the two 3D-CTA readers and between 3D-CTA and 3D-DSA techniques were assessed. In the measurement of the maximum diameter of aneurysms, the measured values of 3D-DSA images were used as thestandard to compare the differences of the maximum diameter of aneurysms in the 3D-CTA VR images between the two 3D-CTA readers
