- W2347677372 abstract "Objective:To investigate the diagnostic value of MRI SPACE-STIR sequence in determination of sacral fracture complicated with sacral nerve injury.Method:7 patients with sacral fracture and sacral nerve deficit from January 2009 to December 2010 were reviewed retrospectively.All cases presented with sacral nerve injury.X-ray,CT,MRI common scan and scan with SPACE-STIR sequence were performed preoperatively.After operation,the clinical data,routine scan images and images from SPACE-STIR sequence were analyzed retrospectively.Result:According to clinical symptoms and physical signs,5 cases had S1 nerve root injury,while 2 cases had S2 nerve root injury.Sacral fracture was determined by X-ray and CT scan,but sacral nerve injury could not be confirmed based on radiographic findings,even MRI could not do so.The preoperative MRI SPACE-STIR sequence showed rupture of sacral nerve root in 2 cases,compression and displacement of sacral nerve in 3 cases,and edema of sacral nerve in 5 cases;and S1 injury in 6 cases,while S2 injury in 1 cases.6 cases with S1 injury and 1 case with S2 injury were confirmed by operation,of these,there were 1 S1 nerve rupture and 1 S2 nerve rupture.The concordance rate between MRI SPACE-STIR sequence and operation in determining sacral nerve deficit was 100%.Conclusion:The 3T MRI SPACE-STIR sequence can directly exhibit sacral nerve injury due to sacral fracture." @default.
