研究设计观察性研究目的主要目的是确定实验体位和标准仰卧位mri在脊柱结构测量上是否存在差异。方法对34例腰痛患者进行回顾性分析。对6个实验体位进行MRI检查。相关测量包括矢状面前（ADH），中间和后椎间盘高度，鞘囊宽度，左/右椎间孔高度（FH）。轴位：椎间盘宽度、左右椎间孔高度。测量L3/L4、L4/L5和L5/S1。每个受试者都作为自己的对照。将实验姿势下的脊柱测量值与标准仰卧姿势下的相同测量值进行比较。结果观察者间信度达94%。在矢状位和轴向位，108个测量中的55个和18个测量中的11个有显著差异。矢状面：a)坐位屈曲时ADH明显小于仰卧位（2.50 mm±0.63）；b)中性坐姿ADH显著小于标准坐姿1.97 mm±0.86；c)坐位屈曲表明双侧FH测量有显著差异；d)与标准仰卧位相比，坐位中性时双侧FH增大0.87 mm±0.17。结论本研究量化了不同实验姿势下脊柱结构测量的差异。直立MRI收集的额外信息可能与导致准确诊断的症状相关，并有助于未来的脊柱研究。
Abstract Study Design Observational Study Objective The primary objective was to determine if there were differences in spine structure measures between experimental postures and standard supine posture MRIs. Methods Thirty-four low back pain patients were included. MRI was taken in 6 experimental postures. The dependent measures includes sagittal view anterior (ADH), middle and posterior disc heights, thecal sac width, left/right foraminal height (FH). In the axial view: disc width, left and right foraminal height. Measures were done L3/L4, L4/L5 and L5/S1. Each subject served as their own control. Spine measurements in the experimental posture were compared to the same measures in the standard supine posture. Results 94% inter-observer reliability was seen. In the sagittal and axial view, 55 of the 108 and 11 of the 18 measures were significantly different. In sagittal view: a) ADH was significantly smaller in the sitting flexed posture by 2.50 mm ± 0.63 compared to the supine posture; b) ADH in sitting neutral posture was significantly smaller than the standard posture by 1.97 mm ± 0.86; c) sitting flexed posture showed that bilateral FH measures were significantly different; d) Bilateral FH was larger in the sitting neutral posture compared to the standard supine posture by 0.87 mm ± 0.17. Conclusions This research quantifies the differences in spine structure measures that occur in various experimental postures. The additional information gathered from an upright MRI may correlate with symptoms leading to an accurate diagnosis and assist in future spine research.
