目的：分析骨样骨瘤的X线、CT、MRI及SPECT-CT融合图像的表现，总结其影像学特征。方法：对我院经手术或穿刺病理证实的28例骨样骨瘤的影像学表现进行回顾性分析。25例行 X 线检查，20例行 CT 检查，7例行 MRI 检查，9例行SPECT-CT图像融合。结果：28例均出现大小不一的圆形或椭圆形瘤巢，直径为2.3～19.5 mm，瘤巢周围伴有不同程度的骨质硬化。 X线对瘤巢显示率为48%（12/25），4例瘤巢中心出现钙化；CT对瘤巢显示率为95%（19/20），出现钙化者16例，2例显示“血管沟征”；SPECT-CT融合图像，9例瘤巢均有显像剂团状异常浓聚，呈“太阳征”；MRI对瘤巢显示率为57%（4/7），7例均显示不同程度骨髓水肿。结论：瘤巢是确诊骨样骨瘤的关键，CT是发现瘤巢的较好方法，SPECT有利于发现隐匿性病变，SPECT-CT融合图像可以明确病变及其累及的范围。

Objective:To analyze the imaging appearances and to evaluate the diagnostic value of X-ray,CT,MRI and fusion imaging of SPECT/CT in osteoid osteoma. Methods:Imaging features of 28 cases of osteoid osteoma proved by surgery and pathology were analyzed retrospectively. 25 cases underwent X-ray,20 cases underwent CT,7 cases underwent MRI and 9 cases underwent image fusion of SPECT/CT. Results:The circular or oval nests were revealed in 28 patients,the diameter of nests ranged from 2.3 mm to 19.5 mm,the margin was clear and with different bone sclerosis surrounded it. X-ray:nests were seen on plain film in 12 cases,4 cases showed calcification. CT:nests were demonstrated in 19 of 20 cases,16 cases showed calcificat-ion,2 cases showed “vascular groove sign”. SPECT/CT:nests showed the imaging agent over concentration in 9 cases,concentra-tion was the most in the center but decreased progressively around it,all 9 cases showed “sun sign”. MRI:nests were seen in 4 of 7 cases (4/7),7 cases showed different degrees of bone marrow. Conclusions:Nest is the key in diagnosis of the osteoid osteoma. CT scan is the more accuracy method to demonstrate the nests. SPECT can discover the occult nidus. SPECT/CT can show nidus clearly and define the boundary of the disease.
