DR、CT检查显示老年糖尿病性足病早期骨质及血管改变情况及其临床应用价值

Early Bone Quality and Vascular Changes of the Elderly with Diabetic Foot Showed by DR and CT Examination and Their Clinical Application Value

目的分析直接数字化X射线摄影系统(DR)、CT检查显示老年糖尿病性足病早期骨质及血管改变情况及其临床应用价值。方法选取本院2018年4月至2020年2月收治且经临床和实验室检查确诊的85例糖尿病性足病患者作为研究对象。重点观察骨组织病变、血管病变及软组织病变等情况。比较糖尿病性足病患者DR与CT征象检出率。结果CT检查对糖尿病性足病患者足部骨质破坏、骨质疏松、软组织病变、血管病变及狭窄、关节脱位及病理性骨折的检出率显著高于DR检查;且诊断大动脉、小动脉钙化、狭窄的准确率均高于DR(P<0.05)。结论DR检查与CT检查均可有效显示糖尿病性足病患者足部病变情况;与DR检查相比,CT检查的检出率更高,图像质量更加清晰,可为临床医师诊治糖尿病性足病提供可靠的影像学依据,值得推广应用。

Objective To analyze the direct Digital Radiography(DR)and CT examination in showing the early bone quality and vascular changes of the elderly with diabetic foot and to analyze their clinical application value.Methods 85 patients with diabetic foot admitted to our hospital from April 2018 to February 2020 and confirmed by clinical and laboratory examinations were selected.Focus on bone tissue lesions,vascular lesions and soft tissue lesions.The detection rates of DR and CT signs for patients with diabetic foot were compared.Results CT examinations have significantly higher detection rates than DR for foot bone destruction,osteoporosis,soft tissue lesions,vascular lesions and stenosis,joint dislocations,and pathological fractures of patients with diabetic foot.The accuracy of CT examination in the diagnosis of calcification and stenosis of large arteries and small arteries is higher than that of DR(P<0.05).Conclusion Both DR and CT examinations can effectively show the pathological changes of the feet of patients with diabetic foot.Compared with DR examination,the detection rate of CT examination is higher,and the image quality is clearer,which can provide reliable imaging basis for clinicians to diagnose and treat diabetic foot,which is worthy of popularization and application.
