| 目的 对比研究数字X线摄影(DR)全脊柱及下肢立位摄影与全景拼接后处理图像的质量,探讨提高图像质量的有效方法,为临床诊断提供参考依据。方法 回顾性分析绍兴市第七人民医院及绍兴文理学院附属医院骨科2020年1—12月的96例脊柱及下肢畸形患者病历资料,按照随机数字表法分为A组与B组各48例。A组行DR全脊柱及下肢立位摄影,B组行DR全脊柱及下肢立位摄影+全景拼接后处理技术处理图像,对比2组的图像质量优良率、图像质量评分、影像信噪比(SNR值)。结果 B组的图像质量优良率(95.83%)高于A组(83.33%),差异有统计学意义(P<0.05)；B组正位、侧位的图像质量评分[(3.80±0.19)、(3.77±0.16)分]均高于A组[(3.15±0.26)、(3.11±0.25)分],差异有统计学意义(P<0.05)；A组与B组正位、侧位的SNR值对比,差异无统计学意义(P>0.05)。结论 全景拼接后处理技术在DR全脊柱及下肢立位摄影中的应用效果显著,能够满足检查需求,提高图像质量,有利于临床诊断。 |

| Objective To compare the image quality of of Digital Radiography (DR) with panoramic mosaic in order to explore the effective methods to improve the image quality,and provide reference for clinical diagnosis.Methods The medical records of 96 patients with spinal and lower limb malformations in Shaoxing Seventh People′s Hospital and the Affiliated Hospital of Shaoxing University from January to December 2020 were retrospectively analyzed,and they were randomly divided into group A and group B with 48 patients in each group according to the random number table method.Group A received DR total spine and lower extremity orthotopic photography,and group B received DR total spine and lower extremity orthotopic photography + panoramic Mosaic post-processing technology for image processing.The excellent rate of image quality,image quality score image signal-to-noise ratio (SNR) of the two groups were compared.Results The excellent rate of image quality in group B (95.83%) was higher than that in group A (83.33%),and the difference was statistically significant (P<0.05).The anteroposterior and lateral image quality scores of group B [(3.80±0.19) point,(3.77±0.16) point] were higher than those of group A [(3.15±0.26) point,(3.11±0.25) point],and the differences were statistically significant (P<0.05).There was no significant difference in the anteroposterior and lateral SNR values between group A and group B (P>0.05).Conclusions The application effect of panoramic stitching post-processing technology in DR spine and lower limb standing photography is remarkable,which can meet the examination needs,improve image quality and benefit clinical diagnosis. |
