摘　　要：目的:通过磁共振影像技术探讨次髎穴的解剖结构及其针刺深度,为临床针刺操作提供准确依据。方法:以41名成年志愿者为研究对象,采用磁共振影像技术采集次髎穴断面图像,明确解剖结构并测量针刺深度,分析针刺深度与性别、身高、体质量及体重指数(BMI)间的差异及相关性。结果:次髎穴断面影像解剖层次为皮肤、皮下组织、胸腰筋膜浅层、竖脊肌、第2骶后孔,与大体标本解剖的观察结果一致。左右次髎穴的针刺深度分别为(4.1±1.0)cm和(4.1±0.9)cm,针刺深度与性别差异无统计学意义,但与体型相关,体质量和BMI越大,其针刺深度值越大。结论:磁共振断面影像可以真实准确地反映次髎穴的解剖结构、层次和毗邻关系,有助于更好地认识次髎穴的解剖结构以及进针深度和角度,可以更好地指导临床针刺操作。Objective:To explore the anatomical structure and needle insertion depth of the Ciliao(BL32)acupoint by magnetic resonance imaging(MRI)technology,and to provide a scientific basis for clinical acupuncture practice.Methods:Forty-one adult volunteers were enrolled to serve as the subjects of the study.Cross-sectional MRI images of the Ciliao acupoint were obtained to identify anatomical structures and measure needle insertion depth.Differences and correlations between insertion depth and variables such as gender,height,weight,and body mass index(BMI)were analyzed.Results:The cross-sectional anatomical layers of the Ciliao acupoint were identified as skin,subcutaneous tissue,superficial layer of the thoracolumbar fascia,erector spinae,and the second posterior sacral foramen,consistent with observations from gross anatomical specimens.The needle insertion depths for the left and right Ciliao acupoints were(4.1±1.0)cm and(4.1±0.9)cm,respectively.There was no statistically significant difference between the needling depths and gender,but a positive correlation was found with body type.Individuals with greater weight and BMI required bigger needle insertion value.Conclusion:Cross-sectional MRI imaging accurately reflects the anatomical structure,layers,and adjacent relationships of the Ciliao acupoint.This method enhances the understanding of its anatomy,needle insertion depth,and angle,providing valuable guidance for clinical acupuncture practice.
