DR与CT在股骨头缺血性坏死诊断中的应用

Application of DR and CT in the Diagnosis of Avascular Necrosis of the Femoral Head

目的:分析股骨头缺血性坏死的临床诊断中应用直接数字化X射线摄影系统(DR)与电子计算机断层扫描(CT)的效果。方法:研究从本院2022年3月~2023年8月接诊的疑似股骨头缺血性坏死患者中随机抽取82例作为试验对象,分别为患者进行DR及CT检查,比较DR与CT检查对于该疾病的诊断效果,分析病变不同时期的影像学特征。结果:在82例疑似患者中确诊68例,DR检查确诊57例(初期9例、早期12例、中期23例、晚期13例),CT检查确诊65例(初期11例、早期14例、中期24例、晚期16例),CT对该疾病检出率高于DR检查,数据差异具有统计学意义(P<0.05)。结论:在股骨头缺血性坏死疾病的临床诊断中应用CT技术的效果优于DR技术,同时CT检查还具有操作简便,无创伤的特点。

Objective:To analyze the effect of direct digital radiography(DR)and computed tomography(CT)in the clinical diagnosis of avascular necrosis of the femoral head.Methods:A total of 82 patients with suspected avascular necrosis of the femoral head were randomly selected from the period from March 2022 to August 2023 as the test subjects,and DR and CT examinations were performed in this group of patients,and the diagnostic effects of DR and CT examinations on the disease were compared,and the imaging characteristics of lesions at different stages were analyzed.Results:Among the 82 suspected patients,68 cases were confirmed,57 cases were confirmed by DR examination(9 cases in the early stage,12 cases in the early stage,23 cases in the middle stage,and 13 cases in the late stage),and 65 cases were confirmed by CT examination(11 cases in the early stage,14 cases in the early stage,24 cases in the middle stage,and 16 cases in the advanced stage),and the detection rate of this disease by CT was higher than that of DR examination,and the data difference met the statistically significant criteria(P<0.05).Conclusion:The effect of CT technology in the clinical diagnosis of avascular necrosis of femoral head is better than that of DR technology,and CT examination also has the characteristics of simple operation and non-traumatic.
