数字化断层融合成像技术在骨折内固定术后骨痂生长情况评估中的应用价值

The application value of digital tomosynthesis in evaluation of the growth of the callus after internal fixation of fracture

目的:对比常规X线DR摄影及X线数字化断层融合成像在骨折内固定术后患者骨生长情评估中的应用价值。方法:选取80例骨折内固定术后的患者,行常规X线DR检查及X线数字化断层融合成像,获得两组图像,由两名高年资主治以上医师对这两组图像质量进行主观对比评价。结果:80骨折内固定术后患者,断层融合图像质量频率分布为:2分59例73.75%,1分17例21.25%,0分4例5.00%。DR图像质量频率分布为:2分43例53.75%,1分26例32.50%,0分11例13.75%,差异有统计学意义(P<0.001)。结论:对骨折内固定术后患者骨痂生长情况显示能力X线数字化断层融合成像优于X线DR检查。

Objective To comparison of the value of X-ray digital photography and digital tomosynthesis in evaluation of the growth of the callus after internal fixation of fracture.Methods 80 cases of fracture after internal fixation were selected out,routine X-ray digital photography and digital tomosynthesis were performed,Get two sets of images.The two groups of images were evaluated subjectively by two senior doctors.Results The frequency distribution of digital tomosynthesis image quality in 80 patients after internal fixation was:2 points of 59 cases 73.75%,1 point of 17 cases 21.25%,and 0 point of 4 cases 5.00%.The frequency distribution of digital photography image quality in 80 patients after internal fixation was:2 points of 43 cases 53.75%,1 point of 26 cases32.50%,and 0 point of 11 cases13.75%.the difference was statistically significant(P<0.001).Conclusion Digital tomosynthesis is superior to X-ray digital photography in demonstrating the ability of Callus growth after internal fixation of fracture.
