摘　　要：急性骨髓炎的影像学诊断技术包括x线平片、超声、CT、MRI及放射性核素显像。早期x线平片的诊断灵敏度低。超声能早期发现深部软组织及骨膜下脓肿，但图像质量取决于操作者的熟练程度。CT能早期观察到微小的骨质改变，但灵敏度较低。MRI可优于其他检查显示髓腔内的病变，但对于死骨、钙化的诊断不如CT灵敏。放射性核素显像剂的种类繁多，灵敏度和特异度各不相同。该文对急性骨髓炎的上述影像学诊断技术进行综述。The imaging diagnostic techniques include X-ray plain film, ultrasound, CT, MRI and radionuclide imaging. X-ray plain film is less sensitive to early acute osteomyelitis. Ultrasound can detect abscesses in the soft tissues and subperiosteal space earlier, but there are variations in image quality based on the different operators＂ levels of proficiency. High-resolution CT can find minimal lesions on bone, but it has a low sensitivity to predict acute osteomyelitis. MRI is superior to other imaging techniques at visualizing bone marrow lesions, but it is less sensitive in detecting sequestrum and calcification than CT. A variety of radionuclide imaging agents have been used in the early diagnosis of acute osteomyelitis in order to find a more sensitive and specific imaging technique. In this paper, different imaging diagnostic techniques of acute osteomyelitis are reviewed.
