摘　　要：目的探讨小儿急性骨髓炎的超声和X-线平片、CT表现及其诊断价值。方法23例小儿急性骨髓炎患者均经穿刺手术病理证实,术前全部患者行X-线平片、增强CT和超声检查。结果X-线对小儿急性骨髓炎的早期诊断灵敏性和特异性较低。CT特点:7d左右出现骨密度不均匀,10d左右显示骨膜反应,2周以内可见骨质破坏。超声特点:最早征象为深部软组织肿胀,4d左右可显示骨膜抬高及少量骨膜下积液。10天后可显示骨皮质破坏,粗糙不平,部分患者骨髓腔内可见不规则无回声区,骨质破坏周围软组织内可见丰富血流信号。结论超声检查对小儿急性骨髓炎有较高的应用价值,可作为小儿急性骨髓炎患者的首选检查方法。Objective To evaluate the imaging feature of acute osteomyelitis of children on ultrasound, X-ray and CT. Methods 23 cases children of surgical proven acute osteomyelitis had ultrasound, X-ray and CT exams. All images were reviewed retrospectively to evaluate the imaging features and their value in diagnosis. Results In early stage, X-ray is of less sentivity and specificity. With CT scan, low density area was found in 7 days, periosteal reaction appeared in 10 days, and bone destruction was found in 2 weeks. With ultrasound, the early sign was deep soft tissue swelling, followed by elevation of periosteum and mild effusion. About 10 days, destruction and surface irregularity of bone could be seen, irregular fluid shadow was found in the bone marrow in some cases. Blood flow signals were found in the soft tissue around the bone destructive area.Conclusions Ultrasound demonstrated more sensitive in detecting acute osteomyelitis in the children than X-rays, ultrasound was recommended as the method of choice in children suspected of acute osteomyelitis.
