"MRI Protocol for Meningitis" Technical Notes
  • Coronal and sagittal thin-section, heavily T2-weighted MRIs may show CSF leaks, which may be the source of infection in cases of recurrent meningitis.
  • Plain and contrast-enhanced MRIs help to depict the complications of meningitis. Such complications include empyema/effusion, cerebritis/abscess, venous thrombosis, venous and arterial infarcts, ventriculitis, hydrocephalus, and edema (with or without cerebral herniation). 
  • The imaging features of meningitis are non-specific, demonstrating abnormal meningeal enhancement. MRI is superior to CT in the evaluation of patients with suspected meningitis 
  •  Add FLAIR post gad in suspected meningeal disease.
  •  For brainstem and midline lesions get sagittal post gad instead of coronal.
  •  For pineal lesions add thin sagittal T2 and T1 pre and post gad images.
  •  Single voxel spectroscopy (TE 35 and 144) on all new mass lesions
  •  Multi voxel only on suspected gliomas. For follow-up use TE 144.
