摘要目的:比较脊柱及下肢立位数字化X线摄影成像（DR）图像与经neoimaging（NE）图像拼接软件处理后图像的质量。方法:回顾性分析浙江省台州医院2019年6-12月经脊柱胸腰椎包括髋关节及下肢全长拼接站立位DR检查的患者163例的临床资料。将其常规DR图像为处理前图像，采用NE图像拼接软件处理后的图像为处理后图像，比较两者图像的质量。结果:DR图像质量Ⅰ级91.41%（149/163）、Ⅱ级8.59%（14/163），NE图像拼接软件处理后图像质量Ⅰ级93.87%（153/163）、Ⅱ级6.14%（10/163），NE图像拼接软件处理前、后的DR图像质量等级比较，差异有统计学意义（χ 2=10.220， P=0.001）。 结论:采用NE图像拼接软件可不再受设备限制而对常规脊柱及下肢立位DR图像进行无缝拼接处理，以此能获得更高质量的图像来满足临床诊断的要求，该研究有创新性。

abstractsObjective:To investigate the image quality of digital radiography (DR) versus neoimaging (NE) technique in imaging of the spine and lower extremities in a standing position. Methods:The clinical data of 163 patients who underwent DR of the thoracolumbar spine and full-length lower extremities in a staining position in June to December 2019 in Taizhou Hospital of Zhejiang Province were retrospectively analyzed. Conventional DR images were designated as pre-processing images. NE software technique-processed images were designated as post-processing images. The image quality between the two techniques were compared.Results:Grade I image quality was observed in 91.41% (149/163) of DR images, and grade II image quality in 8.59% (14/163) of DR images. Grade I image quality was found in 93.87% (153/163) of NE software-treated images, and grade II image quality in 6.14% (10/163) NE software-treated images. There was significant difference in image quality between before and after NE software processing ( χ2 = 10.220, P = 0.001). Conclusion:NE software technique can seamlessly splice conventional DR images of the spine and low extremities in a standing position without being limited by equipment. Thus, high-quality images can be obtained to meet the requirement of clinical diagnosis. This study is innovative.
