The Value of Cerebral CT Angiography with Low Tube Voltage in Detection of Intracranial Aneurysms

Figure 1

Images from a 61-year-old woman with SAH. L-CTA scanning shows an aneurysm ((a), white arrow) at anterior communicating artery and an aneurysm ((a), red arrow) at posterior communicating artery. 3D-DSA depicts the aneurysms at the same locations ((b), white and red arrows). The maximum diameter and neck sizes of anterior communicating artery aneurysm were 7.32 mm and 3.40 mm ((b), white arrow); and those of posterior communicating artery aneurysm were 5.44 mm and 3.86 mm ((b), red arrow).
