Figures
- fig 1.
Patient with an infraclinoid, small aneurysm of the left internal carotid artery–ophthalmic artery.
A, 3D CT angiogram with SSD (superoposterior view) shows a slight laterally bulging contour (arrowhead); however, a significant saccular component cannot be identified.
B, Composite sagittal CPR image clearly shows a small aneurysm (arrow) adherent to the anterior clinoid process.
- fig 2.
;t1Case 1: Patient with an aneurysm of the right internal carotid artery–ophthalmic artery.
A, Right carotid angiogram (left anterior oblique view) shows an aneurysm of the internal carotid artery–ophthalmic artery (arrow).
B, 3D CT angiogram with SSD (superoposterior view) shows an aneurysm (arrow). The fundus cannot be correctly rendered with the SSD technique owing to partial volume effects of the skull base bone.
C, Composite sagittal CPR image clearly shows the fundus and neck of the aneurysm (arrow).
- fig 3.
;t1Case 11: Patient with an aneurysm of the right internal carotid artery–ophthalmic artery.
A, Right carotid angiogram (left lateral view) shows a giant aneurysm.
B, 3D CT angiogram with SSD (superoposterior view) shows an aneurysm. The neck cannot be identified with the SSD technique owing to the giant overlapping fundus.
C, Composite sagittal CPR image clearly shows the neck of the aneurysm with the associated vessel of origin.
- fig 4.
;t1Case 13: Patient with an aneurysm of the internal carotid artery–posterior communicating artery.
A, Right carotid angiogram (left anterior oblique view) shows an aneurysm (arrow).
B, 3D CT angiogram with SSD (superior view) shows an aneurysm (arrow). Mural calcium cannot be well appreciated.
C, Composite sagittal CPR image clearly shows calcification in the wall of the aneurysm (arrow) and parent artery.
