Abstract:
Objective To study the MRI features of sporadic Creutzfeldt-Jakob disease(sCJD). Methods Three patients with clinically diagnosed sCJD underwent MR study,including SE T_1WI,FSE T_2 WI,and DWI sequences.The MR imaging features were analyzed.Results The lesions were not definite either in SE T_1 WI or in FSE T_2 WI,but were prominent in DWI.Abnormal hyperintensive signal appeared in the cerebral cortex,with the frontal,parietal,and occipital lobes being the mostly involved region.The subcortical white matter was normal.The bilateral caudate nuclei and thalami could also be involved.The abnormal signal could be either symmetrical or asymmetrical.There was diffuse atrophy of the brain parenchyma in the late phase of disease,especially in the cortex.Conclusion With the application of MR study,especially the DWI,combined with its characteristic clinical manifestation,the diagnosis of sCJD can be made definitely.
