| 【Abstract】 Objectives: To assess the clinical value of short T1 inversion-recovery(STIR) sequence of MRI in detecting degenerative changes of nonradicular back pain, comparing with TSE-T2WI sequence. Methods: From September 2010 to June 2011, all patients with nonradicular back pain in our hospital were performed MRI. Those patients with the history longer than 1 year were included in this study. A total of 130 patients was recruited, including 89 males and 41 females, with a mean age of 48.3±16.0(17~81 years). MRI scan included sagittal TSE-T1WI, TSE-T2WI, STIR sequence, and axial TSE-T2WI. Data were retrieved and analyzed to compare the ability of STIR and TSE-T2WI sequence in detecting degenerative pathology of back pain. Information of intervertebral lumbar disc degeneration and extrusion was observed and recorded, the facet joint hyperostosis, interspinous ligament edema and subcutaneously soft tissue edema were noted. Chi-square test was performed to compare the ability of STIR and TSE-T2WI in detecting degenerative changes of nonradicular back pain. Results: Of 130 patients with nonradicular back pain, intervertebral disc degeneration, interspinous ligament edema and subcutaneously soft tissue edema were found more at STRI sequence(482, 118 and 25 cases, respectively) than at TSE-T2WI sequence (311, 42 and 8 cases, espectively)(P<0.05). 182 intervertebral disc extrusion and 71 facet joint hyperostosis were detected by both STIR sequence and TSE-T2WI sequence(P>0.05). 5 lumbar spondylolithesis and 19 spinal stenosis were found by both sequences. Conclusions: MRI STIR is of great value in detecting degenerative changes of nonradicular back pain, especially intervertebral disc degeneration, interspinous ligament edema and subcutaneously soft tissue edema. |
