【摘要】：目的:探讨X线数字化断层融合成像(DTS)在诊断足骨骨折中的价值。方法:搜集经临床证实的71例足骨骨折患者的病例资料,所有患者均行数字化X线摄影(DR)、DTS(Volume RAD技术)和CT检查。根据骨折是否累及关节,将患者分为骨折通过关节面组(A组)和骨折未通过关节面组(B组)。根据CT结果,对DR和DTS对两组患者的诊断结果进行比较,并对所有患者的DR和Volume RAD图像质量进行评估(2级评分法)。结果:A组中Volume RAD的诊断符合率(84.21%)高于DR(68.42%),差异有统计学意义(P0.05);B组中DR和Volume RAD诊断结果的差异无统计学意义(P0.05)。71例患者Volume RAD优质图像的构成比(52/71)高于DR(64/71)。结论:X线数字化断层融合成像较DR能够更准确地显示通过关节面的足骨骨折,具有更好的图像质量,是临床诊断足骨骨折的良好辅助检查方法。
[Abstract]:Objective: to evaluate the value of (DTS) in the diagnosis of fracture of foot bone. Methods: the data of 71 cases of foot bone fracture confirmed by clinic were collected. All the patients were examined by digital radiography (DR) and CT. According to whether the fracture involved the joint, the patients were divided into the fracture through the articular surface group (group A) and fracture through the articular surface group (group B). According to the results of CT, the diagnostic results of DR and DTS in the two groups were compared, and the quality of DR and Volume RAD images of all patients were evaluated (grade 2 scoring method). Results the diagnostic coincidence rate of Volume RAD in group 1 (84.21%) was significantly higher than that in group DR (68.42%). There was no significant difference between DR and Volume RAD in group B (P0.05). The ratio of quality images of Volume RAD in 71 patients (52 / 71) was higher than that of DR (64 / 71). Conclusion compared with DR, the image of bone fracture through articular surface can be more accurately displayed by digital tomographic fusion imaging, and it has better image quality. It is a good auxiliary examination method for clinical diagnosis of fracture of foot bone.
