Fluid-attenuated inversion recovery (FLAIR) is a magnetic resonance imaging 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, such as multiple sclerosis (MS) plaques.

DWI directly visualizes the ischemic necrosis in cerebral infarction in the form of a cytotoxic edema, [38] appearing as a high DWI signal within minutes of arterial occlusion. [39] With perfusion MRI detecting both the infarcted core and the salvageable penumbra, the latter can be quantified by DWI and perfusion MRI. [40]

MRI scans showing hyperintensities. A hyperintensity or T2 hyperintensity is an area of high intensity on types of magnetic resonance imaging (MRI) scans of the brain of a human or of another mammal that reflect lesions produced largely by demyelination and axonal loss.
The Exchange sustainability is tied to three funding sources established in statute: (1) the existing 2 percent tax on health insurance premiums sold through Washington Healthplanfinder; (2) reimbursement for activities performed on behalf of Washington Apple Health (the state's Medicaid program), and; (3) an agreed upon carrier assessment.
