Background: The research problem of the previous study was that they only collected the data from the age 18 to 27 years range. In the recent study, they have done the measurement on the X-ray machine but in the present study, we have done the measurement on the MRI machine. Another study in which age ranged from 15-25 years, but in another research the age ranged from 25-82 years, in the study, there was an inclusion of 65 years old subjects but they have done the study in mountain areas. In this study, we have included subjects from 20 to 60 years from the plain area. In this study, we have calculated the Concavity Index from L1 to L5, Intervertebral Disc Height from L3 to L5, and measurement of the lumbar spine's intervertebral canal. Aim & Objectives: The goal is to evaluate the Concavity Index, Intervertebral Disc Height and Intervertebral Canal of lumbar spine using 1.5T MRI on the basis of various parameters such as age, gender, height, weight and BMI. The objective is to calculate concavity Index from L1 to L5, to access IVDH from L3 to L5, to correlate CI, IVDH and IVC relation with age, gender, BMI and measurement of IVC.
