Abstract: Objective To explore the key points of the imaging diagnosis of bone infarction.Methods X-ray,CT and MRI scanning were carried out in 16 cases of clinically and pathologically confirmed bone infarction.The imaging features were analyzed and summarized,and bone infarction was classified into early stage and middle and late stage.The imaging findings were compared with pathologic results.Results The X plain film showed no abnormality and the MRI presented typical map shapedmanifestation in early bone infarction.The X plain film presented spotted high density imaging and the computed tomography showed irregular,multiple high density round focus in middle and late stage of bone infarction.Both stages showed low-signal on T1WI and T2WI.Conclusion MRI possesses a higher sensitivity in the diagnosis of early bone infarction.MR examination should be performed routinely when bone infarction was suspected.
