Interobserver reliability of computed tomography angiography in the assessment of ruptured intracranial aneurysm and impact on patient management

Figure 4 Giant intracranial aneurysms. A: Axial computed tomography angiography (CTA) in maximum intensity projection (MIP); B and C: Three-dimensional (3D)-CTA for giant saccular aneurysm arising from right internal carotid artery and incorporating the origin of anterior cerebral artery and middle cerebral artery (MCA); D: non-contrast computed tomography for another patient shows a well defined lobulated lesion of mixed density in the left temporal lobe with foci of peripheral calcification; E: MIP-CTA axial image shows giant partially thrombosed saccular aneurysm of left MCA; F: 3D–CTA image shows a patent portion of left MCA aneurysm.
