FLAIRavbildninger
FLAIRavbildninger refers to Magnetic Resonance Imaging (MRI) scans that utilize the FLAIR (Fluid Attenuated Inversion Recovery) sequence. This specialized MRI technique is particularly effective at highlighting lesions within the brain and spinal cord. The FLAIR sequence works by suppressing the signal from free-flowing cerebrospinal fluid (CSF). This suppression is achieved through an inversion pulse that is timed to null the signal from the CSF at the time of image acquisition. As a result, areas of abnormal tissue, such as those with edema or inflammation, which have a different water content or chemical environment than normal brain tissue, become more conspicuous against the dark background of suppressed CSF.
FLAIRavbildninger are widely used in the diagnosis and monitoring of various neurological conditions. They are considered
