MRI of brain
see magnetic resonance imaging & MRI neuroimaging
Pathology:
- MRI brain perivascular spaces may be proxy measure of cerebral small vessel disease, glymphatic dysfunction & risk of dementia [2]
- see specific disorder for MRI neuroimaging specifics
Radiology:
- fluid-attenuated inversion recovery (FLAIR) sequence
Notes:
- incidental findings in 10% of brain MRIs (mean age 65 years)
- meningioma 2.5%, mean size 1.3 cm
- cerebral aneurysms 2.3%. mean size 0.45 cm
- arachnoid cysts 1.6%
- pituitary incidentalomas 1.2%
- nearly all remain stable during follow-up [1]
