Abstract:
Objective To evaluate the clinical significance of the distribution characteristics and thickness of lumbosacral canal fat in normal adults,and to assess the relevant factors of the fat thickness.Methods Sagittal images of lumbosacral canal fat on MRI T_(1)WI in 260 normal adults were observed.The distribution characters of the fat were studied on mid-sagittal plane.The thickness of anterior and posterior epidural fat and the canal diameter were measured and analyzed.Results The anterior epidural fat showed a barred or crescent shape and segmental distribution,while the posterior epidural fat had a segmental distribution with a spindle shape.The thickness of the epidural fat varied at different levels.The fat thickness showed no statistical difference between men and women or every age group.Positive linear correlation occurred between spinal canal diameter or obesity index and the thickness of posterior epidural fat.Conclusion The distribution characteristics and thickness of the lumbosacral canal epidural fat can be used as index in diagnosing some spinal canal diseases.
