Abstract
This work aims to evaluate the value and limitations of CT and MRI in visualization of the intracranial parts of normal crnial nerves in living personnel. This study included 32 normal individuals 17 females and 15 males, their ages ranged from 16-60 years. All cases were subjected to full clinical examination, 20 cases were subjected to magnetic resonance imaging and 12 cases were subjected to computerized tomography. All data were analysed to demonstrate the MR findings in comparison with CT to evaluate the role of MRI and CT in visualization of the normal cranial nerves. From this study. It is apparent that MR imaging represents the major advances in visualization of the cranial nerves where most of the cranial nerves could be detected with MRI while with CT, only part of the optic nerve could be detected. MRI does not involve ionizing radiation, beam hardening artifacts, which severely degrade CT images. The direct multiplanar capabilities of MRI together with superior contrast resolution make MRI is more superior to CT in visualization of the cranial nerves.
