Anatomical Radiographic Study of the Lumber Spinal Canal by Magnetic Resonance Imaging

Abstract

The measure of the mid-sagittal diameter of the lumber spinal canal in patient attending the MRI unit complaining of chronic low back pain is important.Lumbar spinal stenosis (LSS) is a Common case relativelydiverse etiologywhich leads to chronic pressureof the caudalequine which forms a bundle within the lowest part of the spinal column. It turnsinto clinically relevant when symptoms of neurogenic claudicating or leg pain appear. Lumbar spinal stenosis can be categorizedon anatomy or etiology and in any case, the diagnosis must take into account both the site and the cause. Plain radiography is of limited value. Myelography withextension views and erect lateral flexion will show the Dynamic component of narrowingwhich cannot berecognize the full worth of on plain computed tomography (CT) or magnetic resonance imaging (MRI). Therefore, in patients with a good history of symptomatic LSS, and a borderline stenosis on MRI, CT Myelography is bespoke as the final imaging investigation prior to surgery.

Method: Sagittal, axial and coronal MRI image of the lumbar spine were obtained for L1, L3, and L5 levels.

Aim of the study: To measure the mid-sagittal diameter of the lumber spinal canal.

Result:Anatomical study of coronal images wasbeneficial in demonstrating the different anatomical structures of the lumbar spine. The mean mid sagittal diameter at the level of L1 was 15.08 millimeters.

Conclusion:No significant sex deference was found in measurement of the mid sagittal diameter, and there was no significant relationship between vertebral heights and mid sagittal diameter of the spinal canal.
