(and intraventricular)

Diffuse Axonal (Shear) Injury (DAI)
Diffuse Axonal (Shear) Injury (DAI)
T2*: Increased sensitivity to hemorrhage
Multiple Sclerosis (MS) Imaging
• MRI is the imaging study of choice
• Help establish “dissemination of lesions in time and space”
• Estimate disease burden
• Identify acute (inflammatory) vs. chronic lesions (enhancement = active inflammation)
Tumefactive MS
Infection• Torch(toxoplasmosis, rubella, CMV and HSV
• Meningitis
• Encephalitis
• Cerebritis and parenchymal abscess
• Empyema (subdural/epidural)
• Cysticercosis.
• Hydatid cyst.
• HIV.
