摘　　要：目的:重新认识腰椎双斜位摄影的重要性及其基础性作用,为腰椎的进一步影像学检查提供先期保证。方法:随机抽取70例腰椎双斜位摄影的平片,分为左后斜位和右后斜位两组,采用全盲法,按照优、良、差3个等级对腰椎进行评价,并分析评价结果。评价项目包括上、下关节间隙清晰程度,椎弓峡部的几何投影,椎弓根的投影位置等。结果:经过统计学分析,两组腰椎斜位影像质量的差异具有统计学意义(P<0.05),腰椎左后斜位组的综合影像质量优于右后斜位组。结论:左后斜位影像质量更有利于影像诊断和相关病变的初筛。分析影响腰椎影像质量的因素,作出调整,可改善影像质量。Objective：To review the importance of double oblique imaging of lumbar vertebrae, and provide preliminary guaranteeing for the further examination of lumbar vertebrae. Methods： Seventy cases of films of double oblique position of lumbar vertebrae were randomly drawed and divided into left - posterior oblique group and right - posterior oblique group. Each lumbar vertebrae was valued in terms of relevant criterions by ablepsia totalis method, and the results of evaluation were further analyzed, including the clear degree between the up and the neath joint space and the geometry projection of vertebral arch isthmus and the projection position of pedicle of vertebral arch. Results： In general, imaging in the left - posterior oblique group was superior to that in the fight- posterior oblique group in quality. Conclusions： Imaging of left posterior oblique more profits diagnostic imaging and preliminary screening of relevant affections. And the quality of imaging can be improved by adjusting the relevant factors.
