Common brain lesions on FLAIR MRI
Fluid-attenuated inversion recovery (FLAIR) is an MRI sequence with an inversion recovery set to null fluids. For example, it can be used in brain imaging to suppress cerebrospinal fluid (CSF) effects on the image, so as to bring out the periventricular hyperintense lesions.
The FLAIR sequence analysis has been especially useful in the evaluation and study of CNS disorders, involving:
● Lacunar infarction
● Multiple sclerosis (MS) plaques
● Subarachnoid haemorrhage
● Head trauma
● Meningitis and other leptomeningeal diseases
