“一体化全景成像人工智能平台”的临床应用价值分析

Clinical Application Value of Integrated Panoramic Imaging Artificial Intelligence Platform

目的探讨“一体化全景成像人工智能平台”中的全长位片拼接软件结合普通DR机在膝关节置换围手术期的应用价值。方法选取2021年12月至2022年12月于江西中医药大学附属医院关节骨科进行TKA或UKA手术的患者30例,采集所有患者术前、术后双下肢全长负重位片,观察组利用本平台软件结合普通DR机进行下肢全长位片的拼接,对照组利用院内全自动拼接设备及软件进行下肢全长位片的拼接,并对拼接好的双下肢全长负重位片胫股角进行测量,后将同一患者观察组所测胫股角数值与对照组进行对比,分析并记录胫股角测量的准确率,然后将两者的成片从图像质量、接缝精度、连接图像对比度等多个方面进行详细比较,以确保图像的准确性和一致性,将两者的成片分为A类图像、B类图像、C类图像。结果使用本平台软件进行术前、术后图像拼接的30例患者其胫股角与院内全自动拼接设备相比较,差异无统计学意义(P>0.05),且其胫股角测量准确率为100%。图像A类图片率为95%,B类图片率为5%,无C类图片。经证实,本平台软件拼接的双下肢全长负重位片质量均优良,其图像清晰度优异,能准确地反映下肢力线,其图像质量差异与院内全自动拼接设备及其软件所拼接图像对比,差异无统计学意义(P>0.05)。结论本平台软件所拼接的双下肢全长负重位片能够精准测量下肢力线及胫股角,对于无自动拼接设备的医院进行膝关节置换术前方案制定、术中指导定位和截骨、术后对患者疗效进行评估等都有着重要的应用价值,确实值得临床推广及应用。

Objectives To explore the application value of the full-length slice splicing software in the"integrated panoramic imaging artificial intelligence platform"combined with the ordinary DR machine in the perioperative period of knee replacement.Methods A total of 30 patients who underwent TKA or UKA surgery in the Department of Joint Orthopedics in the Affiliated Hospital of Jiangxi University of Chinese Medicine from December 2021 to December 2022 were selected.The full-length weight-bearing films of all patients before and after surgery were collected.For the observation group,we used the platform software combined with the ordinary DR machine to splice the full-length films of the lower limbs.For the control group,we used the automatic splicing equipment and software to splice the full-length films of the lower limbs,and measured the tibiofemoral angle of the spliced full-length weight-bearing films of the lower limbs.After that,the tibiofemoral angle measured in the observation group of the same patient was compared with that in the control group,and the accuracy of the tibiofemoral angle measurement was analyzed and recorded.Then,the two films were compared in detail from the aspects of image quality,seam accuracy,and connection image contrast to ensure the accuracy and consistency of the images.The two films were into class A images,class B images,and classC images.Results There was no significant difference between the tibiofemoral angle of 30 patients who used the platform software for preoperative and postoperative image stitching and the automatic stitching equipment in the hospital(P>0.05),and the accuracy of tibiofemoral angle measurement was 100%.The rate of class A images was 95%,the rate of class B images was 5%,and there was no class C image.It was confirmed that the quality of the full-length weight-bearing films of both lower limbs spliced by the software of this platform was excellent,and the image clarity was excellent,which could accurately reflect the lower limb force line.The difference in image quality was not statistically significant compared with the images spliced by the automatic splicing equipment and its softwarein the hospital(P>0.05).Conclusions The full-length weight-bearing films of both lower limbs spliced by the platform software can accurately measure the lower limb force line and tibiofemoral angle.It has important application value for the hospital without automatic splicing equipment to formulate the preoperative plansfor knee replacement,to guide the positioning and osteotomy during operation,and to evaluate the curative effectsfor patients after operation.It is indeed worthy of clinical promotion and application.
