Background: Degenerative diseases, spinal deformity, surgical planning, and postoperative recovery all require proper spinal sagittal alignment. The previous studies have shown the following significant correlation between the thoracic inlet angles, neck tilt in proportion to age but did not show any significant correlation in proportion to gender. Aim & Objective: There have been many studies who have considered Thoracic Inlet Angle, Neck Tilt, T1 slope, Anterior Vertebral Body Line & Spinous Process Line individually & how they affect a population age wise and gender wise. The study was purposed to look into the measurement cervical sagittal parameters and how they affect age and gender individually, in addition to how they interact using MRI. The objective of the study is to evaluate the correlation of TIA, T1 Slope, NT and Anterior Vertebral Body Line with various age groups, to correlate NT, TIA, T1 slope, and AVBL with gender, calculates T1 Slope using TIA and Neck Tilt. Materials and Methods: 106 asymptomatic patients were prospectively selected and their cervical sagittal parameters including TIA, T1 Slope, NT, SPL, AVBL using OSIRIX measuring tools. Cervical and whole body MRI cases were considered and T2 sagittal sequence was used to measure the parameters.T1 intensity image produced with a TE/TR of 9.7/550 intensity image was produced; the slice thickness was 3.0mm. Using the scaling option from the software, measure the angles and lengths of the desired parameters.
