摘　　要：目的对比分析超声、数字X线摄影(DR)及磁共振成像(MRI)对膝骨性关节炎的诊断价值。方法选取2017年6月至2019年6月我院收治的KOA患者70例,均行DR、超声及MRI检查,比较三种检查方法对各KOA征象的检出率。结果DR检查对于KOA骨质增生、骨质疏松等骨性病变的检出率分别为85.71%、54.29%,均明显高于超声(65.71%、0.00%)及MRI检查(68.57%、0.00%),有统计学差异(P<0.05)。而在非骨性改变的显示上,超声与MRI对髌上囊积液、滑膜增厚、关节软骨退变、软骨下骨破坏、半月板退变、腘窝囊肿、韧带损伤的检出率分别为81.43%、81.43%、88.57%、51.43%、35.71%、48.57%、11.43%与82.86%、84.29%、91.43%、54.29%、44.29%、48.57%、14.29%,均明显高于DR检查(P<0.05);但超声与MRI比较无统计学差异(P>0.05)。结论DR、超声及MRI均对KOA有重要诊断价值;对于非骨性改变的,超声及MRI较DR片具有明显优势,而DR片能够更好地检出骨性改变;三者互补应用,有助于KOA的准确诊断。Objective To compare the diagnostic value of ultrasound,digital radiography(DR)and magnetic resonance imaging(MRI)for knee osteoarthritis(KOA).Methods Seventy patients with KOA who were admitted to the hospital from June 2017 to June 2019 were selected.All of them underwent DR,ultrasound and MRI.The detection rates of signs of KOA were compared among the three methods.Results The detection rates of hyperostosis and osteoporosis by DR were 85.71%and 54.29%,respectively,which were significantly higher than those by ultrasound(65.71%,0.00%)or MRI(68.57%,0.00%)(P<0.05).For the display of non-bony changes,the detection rates of supracondylar effusion,synovial thickening,articular cartilage degeneration,subchondral bone destruction,meniscus degeneration,popliteal cyst and ligament injury by ultrasound and MRI were 81.43%,81.43%,88.57%,51.43%,35.71%,48.57%,11.43%and 82.86%,84.29%,91.43%,54.29%,44.29%,48.57%,14.29%,respectively,which were significantly higher than those by DR(P<0.05).However,there was no significant difference between ultrasound and MRI(P>0.05).Conclusion DR,ultrasound and MRI are of great diagnostic value for KOA.For non-bony changes,ultrasound and MRI have obvious advantages over DR,while DR can better detect bony changes.The complementary application of the three methods can help the accurate diagnosis of KOA.
