DR组织均衡技术在足部摄影的应用价值

Clinical application value of DR tissue equalization technique in foot radiography

目的探讨数字化X线摄影(DR)中,运用组织均衡技术(tissue equalization,TE)在足部摄影的应用价值。方法 200例足伤病人通过数字化X线摄影,行足部正斜位摄影,所有病人正斜位影像均进行DR组织均衡均技术后处理。对足部常规DR影像和组织均衡均技术后处理影像质量进行评价,并进行统计学处理。结果运用组织均衡技术后处理影像质量与常规DR影像相比显示全足骨结构更清晰、层次更丰富,两者存在差异,有统计学意义。结论 DR组织均衡均技术对体厚差别较大的足部影像有较大的临床价值。

Objective To study the clinical cpplication value of digital radiography tissue equalizating（DR TE） technique in Foot radiography.Methods These images collected form DR foot images of 200 cases were processed by with tissue equalization technique and compared with standard DR images.Results Tissue equalization technique was obviously excellence to conventional X-ray examination on displaying the structure of foot,the difference was significant statistically.Conclusion The DR tissue equalization technique has better value in displaying the image of foot which is difficulty to be obversed due to the influence of body thickness.
