Abstract
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.关键词
