Abstract:
Objective To investigate the diagnostic value of MRI on Creutzfeldt-Jakob disease(CJD).Methods The imaging data of 15 patients with CJD were analyzed retrospectively.Results In the 15 cases,the diagnosis was clinical probable CJD 10 cases,maybe CJD 5 cases.There was no abnormal signal found by routine T 1WI and T 2WI scanning in the 15 cases.DWI showed that 10 cases had hyperintense abnormalities in both the cerebral cortex and the striatum,5 cases had hyperintense abnormalities only in the cerebral cortex.The hyperintense abnormalities were symmetric in 8 cases,but were asymmetric in the other 7 cases.1H-MRS were applied in the 4 cases and showed that N-acetylas partate(NAA),NAA/creatine(Cr) were decreased to some extent.Choline(Cho),Cho/Cr were decreased in 2 cases and increased in 2 cases.mI peak did not appear in all 4 cases.Conclusion MRI,especially DWI and 1H-MRS give can valuable information in detecting and diagnosing CJD early.
