263. Detection of scoliosis curve flexibility by means of MRI

Abstract

BACKGROUND CONTEXT The majority of scoliosis patients are subject to tremendous amounts of x-ray radiation in order to establish the diagnosis or follow the progression of the curves. There are different remedies to reduce the dose of delivered radiation or protect the body against such exposures. In addition, Bi-dimensional slot scattered technique (EOS) has provided some advantages, however, it is not available at all spine centers. The scoliosis patients are frequently requested to obtain MRI to discover neural axis abnormalities. As an attempt to find other alternatives for x-ray imaging, some authors demonstrated that the measured curve in the standing x-ray is correlated with the magnitude of the curve in the supine MRI. PURPOSE The supine MRI can illustrate the curve flexibility as obviously as the bending x-ray images in patients with idiopathic scoliosis. STUDY DESIGN/SETTING Retrospective analysis of imaging records. PATIENT SAMPLE N/A OUTCOME MEASURES N/A METHODS In this study, the imaging of 103 preoperative patients with idiopathic scoliosis were reviewed. The Cobb angle in the bending position toward the convex side was measured by an orthopedic resident. The curve of scoliosis in supine MRI and between the same levels was obtained by a spine flow, separately. The measured angles were entered into SPSS and the assessment was performed by the other researcher. RESULTS A total of 103 patients (33 male, 70 female) with idiopathic scoliosis from age 5 to 35 (mean 16.5 years) were included in the study. Pearson correlation between the curve angle in MRI and bending x-ray was calculated. (0.915°, P-value CONCLUSIONS To diminish the radiation exposure in patients with scoliosis, we can take the advantages of the correlation between bending curve and supine MRI angle measurements. Consequently, the main goal of bending views to assess curve flexibility might be relatively fulfilled by supine MRI images, consistently.
