摘要
目的评价正常成人腰骶段椎管内脂肪的分布特征和厚度范围的临床价值,探讨与脂肪厚度相关的影响因素。方法在MR正中矢状面T1WI上观察了260例正常成人腰骶段椎管内脂肪的分布特点,并测量脂肪厚度及椎管前后径,对测量结果行统计学分析。结果MR正中矢状面上硬膜外腹侧脂肪多呈带状或新月状,背侧脂肪呈梭形节段性分布。不同水平脂肪厚度正常值范围不等,但在性别和年龄组间均无统计学差异。体质量指数、椎管前后径与硬膜外背侧脂肪厚度呈正线性相关关系。结论正常成人腰骶段椎管内脂肪的分布特征和厚度范围可为临床诊断某些椎管疾病提供参考依据。
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 T1 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.
