MRI OF LUMBO-SACRAL SPINE Technique:- Sagittal, coronal and axial images of the lumbar spine were visualized using T1 and T2 weighted images. Intravenous contrast was not given. sagittal & coronal MR Myelography images. Findings: There is loss of lumbar lordosis . Status post surgery- post operative changes are noted at L5-S1 levels. At L2-L3 and L3-L4 levels- Diffuse circumferential disc bulge with central disc protrusion causing indentation on thecal sac without any exiting nerve root compression.. At L4-L5 level- disc desiccation . Diffuse disc bulge causing spinal canal and bilateral neural foraminal stenosis and indenting adjacent traversing and bilateral exiting nerve roots. At L5-S1 levels- disc desiccation. Diffuse disc bulge causing spinal canal and bilateral neural foraminal narrowing indenting adjacent traversing exiting nerve roots. Rest of the intervertebral discs and vertebral bodies appear normal in signal intensity. The facet articulations and rest of the neural foramina appear normal. The spinal cord , conus shows normal signal intensity. The pre and paravertebral soft tissues are unremarkable. IMPRESSION:  Status post surgery.  At L2-L3 and L3-L4 levels- Diffuse circumferential disc bulge with central disc protrusion causing indentation on thecal sac without any exiting nerve root compression.
