Image Processing Application

Bone-free 3D computed tomography angiography (CTA) can be carried out to image cerebral aneurysms near the skull base when the elimination of bones is surgically required. The maximum intensity projection (MIP) images were initially obtained using the application. Further post-processing was performed to obtain the MIP and volume-rendering (VR) images. This technique did not increase radiation exposure to patients, and remnant bones in the initial MIP images automatically acquired by the application for bone elimination could be easily removed through post-processing. Although parts of vessels were sometimes removed from the image along with the bones, these could be quickly and easily recovered through post-processing. Thus, bone-free 3D CTA and conventional 3D CTA are complementary tools for imaging cerebral aneurysms near the skull base prior to surgery. This application could also eliminate clips in cases of clipped cerebral aneurysms, and it could improve the accuracy of detecting remnant necks after clipping surgery.

The Relationship

Objective: To investigate the association of high septal deviation with the olfactory fossa depth and Gera angle. Methods: Fifty-four computed tomography scans of patients with high septal deviation were evaluated. The olfactory fossa depth and Gera angle were measured. The values of the deviated and nondeviated sides were compared. Results: No association between high septal deviation and the olfactory fossa depth and Gera angle was found. Conclusion: High septal deviation does not affect the olfactory fossa depth and Gera angle. In other words, the olfactory fossa depth and Gera angle have no association with the high septal deviation.
