Clinical question: MS versus stroke. Signs and symptoms: Inability to walk. Nonenhanced brain MRI:Examination is performed without intravenous contrast due to patient's refusal.Examination of the cervical spine was not performed due to patient's claustrophobia.Negative diffusion weighted images.Examination is degraded due to motion artifact however diagnostic.There is normal anatomical morphology and normal signal intensity of brain parenchymal on all MRI sequences.There is a slight prominence of cortical sulci for patient's stated age. The ventricular system remains within normal and maintained midline.There is normal myelination of brain parenchyma. The CSF spaces remain widely patent and unremarkable.The signal void of major intracranial arterial branches are identified. The signal intensity of intracranial venous sinuses are beginning normal.Unremarkable images through the orbits, paranasal sinuses and mastoid air cells and
Unremarkable nonenhanced brain MRI.
