Background: Evaluation of craniovertebral junction (CVJ) diseases involves the use of a wide range of parameters and craniometric measures. As a result, figuring out the range of typical craniometric readings is critical. Objective: The aim of the current work was to determine the morphometric reference values of the bony structures in the CVJ by computed tomography (CT) and magnetic resonance imaging (MRI) in normal people who have no history of congenital or acquired abnormalities of craniocervical junction (CCJ) Patients and methods: In the Radiology Department, Mansoura University, 60 people participated in this study (30 by CT and 30 by MRI) at different ages with no history of CCJ abnormalities. These individuals were divided into three age groups. Retrospective analysis was performed on the MDCT and MRI scans. A total of 14 midsagittal parameters and 2 coronal parameters were investigated. The data were analysed statistically. Results: C.T. for PAI, BAI, BDI, OPFD, and OPFB: there were statistically significant differences among the three age groups tested. The ADI was statistically substantially higher in the group of people under the age of 18, then in the group of people between the ages of 18 and 60, and finally in the group of people older than 60. All other parameters, on the other hand, showed no statistically significant differences. MRI for PAI, BAI, and BDI: the three groups investigated showed statistically significant differences. Conclusion: We found that some parameters show statistically significant differences between different age groups which are consistent with previous studies and that there is no significant differences between this study in Egyptian people and previous studies in western population with respect to several parameters in CVJ osteometry so that researchers studying pathology in this region will find the normal reference ranges valuable.
