Abstract:
Objective To study CT and MRI value in diagnosis of osteoblastoma,in order to achive more information about the disease. Methods The clinical,CT,MRI and histological data of 12 patients with osteoblastomas. Results(1)There were 6 patients wereexamined by CT,the lesions showed mainly lytic with varying degrees of matrix mineralisation,and mild adjacent reactive sclerosis;(2)10 patients were examined by MRI(included 4 patients who have been examined by CT),the lesions presented mixed signal intensity with compart,slightly low and intermediate signal intensity on T_1-weighted images,high signal intensity on T_2-weighted images were found in 9 cases and mainly low signal intensity was found in 1 case.8 cases showed clear low signal intensity surrounding the lension borh on T_1 and T_2,2 cases showed blurry high signal in the adjacent tissue;(3) The tumors presented moderate enhancemen with low dense area inside the lesions after injection of contrast media. Conclusion Osteoblastomas have classical features on CT,while show no characteristic appearances on MRI.
