[Abstract] Objective: To assess the value of MR volumetric isotropic T2-weighted acquisition (VISTA) in evaluating scoliosis.Materials and Methods: VISTA images were obtained from 30 patients with scoliosis using a 1.5 T superconduct scanner and phase-array whole-spine coil. The segmentedly acquired source data of the spine were postprocessed to create the panoramic images with curved multi-planar reconstruction (cMPR) after seamless splicing. An overall perspective of the spine and spinal cord was showed in the panoramic images, which were scored as grade I, grade II, or grade III based on the provided diagnostic information quality (DIQ).Results: The DIQ was graded III in all the 30 patients based on the VISTA-cMPR images. The perspective of the whole spine and spinal cord was visualized in the all the 30 cases, 23 of which were "S" shaped scoliosis of the whole spine, 3 of cervicothoracic scoliosis, 3 of thoraco-lumbar scoliosis, and 1 of lumbar scoliosis with segment. Of the 30 cases, hemivertebrae deformity was identified in 3, Chiari malformation in 4, syringomyelia in 8, tethered syndrome in 3, and hemangioblastoma and astrocytoma in cervico-thoracic cord in 1, respectively. The panoramic findings of the scoliosis on both vertebral and spinal cord anomalies were surgically proved. The DIQ grading among the 30 patients was I in 26, II in 3, and III in 1, respectively, based on the conventional MRI . The difference of independent test between conventional MRI and VISTA-cMPR was statistically significant (χ2=28.06, P<0.01).Conclusion: MR-VISTA plays a vital role in both the diagnosis and pre-surgical evaluation of scoliosis.
