white matter hyperintensities (IMAGE) Keck School of Medicine of USC Caption An example of white matter hyperintensities (WMHs) on a FLAIR MRI scan in an older adult. FLAIR MRI is a technique that is particularly good at detecting fluid in the brain. It helps researchers see areas of the brain that might be damaged by making the cerebrospinal fluid appear dark while the surrounding tissue remains light and detailed. This contrast makes it easier to identify abnormalities or injuries; WMHs appear as bright, patchy regions in the brain tissue. Credit Jennifer K.
