小儿急性骨髓炎超声诊断和X线、CT对照分析

Diagnosis of acute osteomyelitis in children with ultrasound,X-ray and CT

目的分析小儿急性骨髓炎超声诊断和X线、CT特点,总结小儿急性骨髓炎的诊断经验。方法选择2012年2月至2015年8月沈阳市儿童医院收治的急性骨髓炎患儿28例为研究对象,均采用超声、X线、CT结合诊断。结果 CT检出的骨改变表现总个数高于X线、超声,CT检出圆形类圆形骨破坏、特殊形态骨破坏等骨质改变表现37项,X线15项,超声20项。CT发现骨膜增生表现11项,X线6项、超声0项。CT对特殊形态骨破坏检出率高于X线、超声,CT对残存膨胀骨骨壳破坏检出率高于X线,CT对骨膜增生、骨膜与皮质改变检出率高于超声,X线骨膜与皮质改变检出率高于超声,差异有统计学意义(P<0.05)。结论不同时间段,疾病变化发展影响,超声、X线、CT对软组织以及骨膜与皮质改变存在差异。超声诊断和X线、CT均可用于小儿急性骨髓炎的诊断,CT获得的信息更多。

Objective To analyze the features of ultrasound,X-ray and CT in the diagnosis of acute osteomyelitis in children,and to summarize the diagnosis experience.Methods A total of 28 children with acute osteomyelitis treated in Shenyang Children's Hospital from February 2012 to August 2015 were selected as the research subjects,and all of them were diagnosed by ultrasound,X-ray and CT.Results The number of bone change detected by CT was higher than that by X-ray and ultrasound.A total of 37 items of round bone destruction and special bone destruction were detected by CT,while 15 by X-ray and 20 by ultrasound.Eleven items of periosteal proliferation was found by CT,and 6 by X-ray and none by ultrasound.The rate of CT in detecting special bone destruction was higher than that of ultrasound and X-ray.The rate of CT in detecting remnant expansion bone shell destruction was higher than that of X-ray.The rate of CT in detecting periosteal proliferation,periosteal change and cortex change was higher than that of ultrasound.The rate of X-ray in detecting periosteal and cortex change was higher than that of ultrasound.All the differences were of statistical significance(P<0.05).ConclusionIn different time periods,the changes of the disease were influenced by the changes of ultrasound,X-ray and CT on the soft tissue and the changes of the periosteum and cortex.Ultrasound,X-ray and CT can be used in the diagnosis of acute osteomyelitis in children,and CT gives more information.
