高场强MRI与MSCT在诊断膝关节隐匿性骨折中的应用价值及影像学特征分析对比OA
Analysis Comparison of the Application Value and Imaging Characteristics of High Field MRI and MSCT in the Diagnosis of Occult Fractures of Knee Joint
目的:分析高场强核磁共振成像(MRI)与多层螺旋计算机断层扫描(MSCT)在诊断膝关节隐匿性骨折中的应用价值及影像学特征.方法:回顾性分析2022年 4月—2024年 4月邹城市人民医院接收的80例高度疑似隐匿性骨折患者资料,所有患者均接受高场强MRI与MSCT检查.以关节镜结果为金标准,比较高场强MRI与MSCT检查膝关节隐匿性骨折的阳性诊断结果及病变信息诊断结果,计算诊断效能,包括灵敏度、特异度、准确度、阳性预测值、阴性预测值.结果:高场强MRI检查隐匿性骨折阳性的灵敏度、特异度、准确度、阳性预测值、阴性预测值依次为95.31%、93.75%、95.00%、98.39%、83.33%,与MSCT的 92.19%、93.75%、92.50%、98.33%、75.00%比较,差异均无统计学意义(P>0.05).高场强MRI与MSCT检查关节积液、韧带损伤、骨髓水肿、半月板损伤、肌腱断裂的灵敏度、特异度、准确度、阳性预测值、阴性预测值比较,差异均无统计学意义(P>0.05).结论:高场强MRI与MSCT在膝关节隐匿性骨折及其病变信息的诊断中具有相似的诊断价值,均能对关节积液、韧带损伤、骨髓水肿、半月板损伤、肌腱断裂等病变进行准确评估.
Objective:To analyze the application value and imaging features of high field magnetic resonance imaging(MRI)and multi-slice spiral computed tomography(MSCT)in the diagnosis of occult fracture of knee joint.Methods:Data of 80 patients with highly suspected occulted fractures admitted to Zoucheng People's Hospital from April 2022 to April 2024 were retrospectively analyzed.All patients were examined by high field MRI and MSCT.Using arthroscopic results as the gold standard,the positive diagnostic results and lesion information diagnostic results of high-field MRI and MSCT were compared,the diagnostic efficiencies were calculated,including sensitivity,specificity,accuracy,positive predictive value,negative predictive value.Results:The positive sensitivity,specificity,accuracy,positive predictive value,negative predictive value of high field intensity MRI for occult fracture were 95.31%,93.75%,95.00%,98.39%,83.33%,respectively,compared with 92.19%,93.75%,92.50%,98.33%,75.00%of MSCT,there were no significant differences(P>0.05).There were no significant differences in sensitivity,specificity,accuracy,positive predictive value and negative predictive value between high-field MRI and MSCT in detecting the lesions of occult fractures(joint effusion,ligament injury,bone marrow edema,meniscus injury,tendon rupture)(P>0.05).Conclusion:High field MRI and MSCT have similar diagnostic value in the diagnosis of occult fracture of knee joint and its pathological information,and both can accurately evaluate joint effusion,ligament injury,bone marrow edema,meniscus injury,tendon rupture and other lesions.
