ABSTRACT

The objective of this research work is to analyses the use of MRM (magnetic resonance myelography) along with the CMR LS-Spine (conventional magnetic resonance lumbosacral spine) examination in patients of suspected degenerative spine disease.
Result: - A prospective analysis of 42 consecutive patients of conventional MR LS spine along with additional complimentary MR myelography TES sequence. The contribution of MRM is great in CMR LS spine. 42 patients by correlation with team of 2 radiologists (R1 & R2), (19 positive and 23 negative result) & (15positive and 27negative) respectively.
RADIOLOGIST 1: - Out of 42 patients 20 patients gives the positive result and 22 patients gives negative result i.e. 47.62% and 52.38% respectively. The conventional MR LS spine and MRM are independently diagnosed one after another (firstly conventional MR LS spine and then HRM and all the diagnostic information has kept documented.
RADIOLOGIST 2: - Out of 42 patients 18 patients gives the positive result and 24 patients gives negative result i.e. 42.85 % and 57.14% respectively. The conventional MR LS spine and MRM are independently diagnosed one after another (firstly conventional MR LS spine and then HRM and all the diagnostic information has kept documented.
The kappa coherence agreement between the two radiologist (radiologist R1 & radiologist R2), for MRM finding to have MRM finding other than that of CMR LS spine is good agreement with kappa value, 028.
The result of the percentage of the spinal cord termination level variation level at the anatomy of spinal canal in three categories have

Above the level of T12-L1 IVD level. = (17/42) x 100 = 40.47%
At or in between the of L1 to L2 vertebrae level. (21/42) x 100 = 50%
Below the level of L2-L3 IVD level. (4/42) x 100 = 9.52%

The patients having PIVD, Disc Bulge, Straitening of spine, lumbar canal stenosis & Nerve root compression in both CMR LS spine & MRM respectively. The PIVD and diffuse disc bulge is clearly seen in CMR LS spine. But in the degenerative spinal disc disease like Straitening of lumbar spine, lumbar canal stenosis & Nerve root compression shows equivalent or even better diagnosis in MRM compared to CMR LS spine.
The result shows that patients having 30.9% PIVD problem (13/42), 45.2% (19/42) in diffuse disc bulge, straightening of lumbar spine and lumbar canal stenosis. Most of the patient shown problem of nerve root compression in 22patient out of 42 patients i.e. 52.3%.
