Objectives To evaluate the image quality, radiation dose and diagnostic accuracy of low kVp and low contrast material volume cerebral CT angiography (CTA) in intracranial aneurysm detection. Methods One hundred twenty patients were randomly divided into three groups ( n  = 40 for each): Group A, 70 ...
