ABSTRACT



Objective: To validate the additional merits of two-dimensional(2D) single thick-slice Magnetic Resonance Myelography (MRM) in spinal imaging.
Materials and Methods: 2D single thick-slice MRM was performed using T2 half-Fourier acquisition single-shot turbo spin-echo(HASTE) sequence in addition to routine Magnetic resonance (MR) sequences for spine in 220 patients. The images were evaluated for additional diagnostic information in spinal and extra-spinal regions. Athree-point grading system was adopted depending upon the utility of MRM in contributing to the detection of spinal or extra-spinal findings. Grade 1 represented no contribution of MRM while grade 3 would indicate that it was essential to detection of findings.
Results: Utility of MRM in spine was categorized as grade 3 in 10.9% cases (24/220), grade 2 in 21.8% (48/220) cases and grade 1 in 67.3% cases (148/220). Thus, the overall additional merit of MRM in spine was seen in 32.7% (72/220) of cases. Besides in 14.1% cases (31/220) extra-spinal pathologies were identified.
Conclusion: 2D single thick-slice MRM could have additional merits in spinal imaging when used as an adjunct to routine MR sequences.
