Creutzfeldt-Jakob disease: serial changes on diffusion-weighted MRI
1Department of Radiology, Kanazawa Medical University, Ishikawa, Japan. m-matoba@kanazawa-med.ac.jp
Abstract:
We present serial changes on diffusion-weighted MRI (DWI) in a patient with Creutzfeldt-Jakob disease (CJD). DWI revealed serial changes of abnormal hyperintense lesions that had become more extensive and conspicuous with progression of neurologic findings, more sensitively than conventional MRI. In the late stage, disappearance of abnormal hyperintense lesions on DWI was observed. DWI proved to be particularly useful for monitoring the progression of CJD.
Insights
Diffusion-weighted MRI (DWI) effectively tracks Creutzfeldt-Jakob disease (CJD) progression by showing evolving brain lesions. DWI detects changes earlier and more sensitively than conventional MRI, aiding in disease monitoring.
Area of Science:
- Neuroimaging
- Neurology
- Radiology
Background:
- Creutzfeldt-Jakob disease (CJD) is a rapidly progressive neurodegenerative disorder.
- Accurate monitoring of CJD progression is crucial for patient management and research.
Observation:
- Serial diffusion-weighted MRI (DWI) scans were performed on a patient diagnosed with CJD.
- Conventional MRI sequences were also utilized for comparison.
Findings:
- DWI demonstrated serial changes in abnormal hyperintense lesions, correlating with neurologic decline.
- These DWI findings were more extensive and conspicuous than those on conventional MRI.
- In advanced stages, a resolution of hyperintense lesions on DWI was noted.
Implications:
- DWI is a highly sensitive tool for detecting and monitoring the evolution of CJD.
- Serial DWI imaging can provide valuable insights into the disease course and response to potential therapies.
- This technique enhances the ability to track CJD progression compared to standard MRI methods.
