三线影在腰椎X线影像解剖中的意义

目的 :研究腰椎椎体三线影的X线影像解剖基础。方法 :通过对 60套椎骨标本外形和X线影像的对比观察 ,探讨三线影的成像机理。分析 2 0 0例腰椎正侧位X线片 ,3 5例双斜位片 ,观测三线影的显示情况。结果 :椎体上、下面的X线影像可表现为单线影、双线影和三线影 ,三线影是基本表现。 2 0 0例X线片 ,正位有 197例 (98.5 % ) ,至少一个椎体终板存在三线影 ,共计 882个 ,侧位片则均可见三线影 ,共计14 2 2个椎体终板。结论 :椎体终板的三线影成像规律对腰椎X线影像诊断有重要价值。

The significance of the three-line imageg in X-ray imzgoing anatomy of the lumbar vertebrae

Objective:To study the X ray imaging anatomy basis of the three line image of the lumbar vertebrae.Methods:The shapes and X ray films of 60 cases lumbar vertebrae specimens were observed and analyzed.The anteroposterior and lateral X ray films of 200 lumbar vertebrae specimens and oblique X ray films of 35 cases were also observed to find the incidence of the three line image.Result:The X ray images of the superior and inferior end plates of the lumbar vertebrae showed one,two or three line image.The three line image was the basic.Of 200 cases X ray films,197 cases(98.5%) had at least one end plate showing three line image at anteroposterior X ray films,counting up to 882 end plates,and all lateral X ray films showed the three line image,counting up to 1 422 end plates.Conclusions:It is very important to know three line image of the lumbar vertebrae in the X ray diagnoses of the lumbar vertebrae.
