Introduction
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]
