摘要/Abstract

摘要： 目的探讨磁共振成像（MRI）技术在膝关节隐匿性骨折临床诊断中的应用价值。方法从我院2020年7月—2022年7月期间接诊的膝关节隐匿性骨折病例中随机抽取78例作为研究对象,所有病例均开展MRI、CT检查,分析并比较MRI和CT检查对该病变的检出率。结果在78例膝关节隐匿性骨折病例中,MRI检查确诊76例,检出率97.44%,CT检查确诊61例,检出率78.21%,MRI检查对该疾病的检出率相比CT检查更高,差异有统计学意义（P<0.05）。MRI对半月板损伤、关节腔少量积液、韧带损伤、骨折塌陷及水平错位检出率相比CT更高,差异有统计学意义（P<0.05）,两种检查方式在严重骨折检出率差异较小,差异无统计学意义（P>0.05）。结论在膝关节隐匿性骨折的临床诊断中应用MRI对疾病检出率较高,且操作简便,在临床中具有较高的推广价值。

Abstract: Objective To investigate the application value of magnetic resonance imaging(MRI)in the clinical diagnosis of occult knee fractures. Methods A total of 78 cases of occult knee fracture received by our hospital from July 2020 to July 2022 were randomly selected as research subjects,and MRI and CT examinations were performed on all cases,and the detection rates of MRI and CT examination were analyzed and compared. Results Among the 78 cases of occult knee fracture,76 cases were confirmed by MRI examination,with a detection rate of 97. 44%,and 61 cases by CT examination,with a detection rate of 78. 21%,and the detection rate of MRI examination for this disease was higher than that of CT examination,and the difference was statistically significant(P<0. 05). MRI had higher detection rate of meniscal injury,small effusion in the joint cavity,ligament injury,fracture collapse and horizontal misalignment than CT(P<0. 05),and the difference in the detection rate of severe fractures was small and not statistically significant(P>0. 05). Conclusions The application of MRI in the clinical diagnosis of occult knee fracture has a high disease detection rate and simple operation,and has high promotion value in clinical practice.
