Characterization of normal lumbar spine in Sudanese population using magnetic resonance images

Abstract

Introduction: Various medical imaging technique used in radiology to investigate the anatomy and physiology of the body in both health and disease. The main principle of magnetic resonance images (MRI) use strong magnetic field and radio waves to form an image for a certain area in the human body. The technique widely used in the hospital for medical diagnosis. In clinical practice, the MRI is employed for the assessment of lower back in the human body. Knowledge of lumbar the spine character is important for the clinical assessment of spine diseases. Materials and Methods: This study consisted Fifty nine consecutive patients gender both males and females Ages between 18-45 years adult with no known history of lumbar spine diseases underwent lumbar spine MRI sagittal T1, T2-weighted images. MRI machine 1.5 Tesla was used the selected sequences were Scout: axial sagittal, and coronal. Objective: The aims of this study were to establish a normal range of values for lumbar spine length (high) and classify the signal intensities by use of MRI for normal Sudanese adult with no known history of lumbar spine diseases. Result: Of this study revealed Correlation between measurement of the lumbar spine and body indices. The data were expressed as means ± standard deviation (S.D). Lumbar spine length (high) and signal intensity were analyzed as combine group (male + female) as well as the total sample. The data statistical analyses were performed using excel software programmed and statistical analyses were performed using the independent sample t -test, simple correlation (SPSS software version 20 USA) statistical significance was assumed at P . Conclusion: The lumbar spine length (high) for Sudanese adult were found to be in the ranges of (13.8-23.4) cm with mean = 16.9 ± 1.7 S.D. the signal intensities for lumbar spine in MRI fast spin echo image (FSE) were found to be in the ranges (61-163) pixel value (45-110) pixel value for vertebrae and inter vertebral disc respectively.
