RESUMO
Objective: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.
