What is a flair signal in the brain?
What is a flair signal in the brain?
Fluid-attenuated inversion recovery (FLAIR) is a magnetic resonance imaging (MRI) sequence that produces strong T2 weighting, suppresses the CSF signal, and minimizes contrast between gray matter and white matter.
What does punctate lesion mean?
Abstract. Background: Punctate white matter lesions (PWMLs) are small focal patches of increased signal intensity (SI) on T1- and decreased SI on T2-weighted magnetic resonance imaging (MRI). To date, there have been few reports of PWMLs in term born infants.
Are white matter lesions normal?
Combining these three studies together, it is clear that small (punctate) white matter lesions are extremely common, they are found in roughly half of the otherwise healthy population in their 40’s, and WML increase with age.
Are white matter lesions reversible?
White matter hyperintensities in patients with RCVS are partially reversible, which should be known by both clinicians and patients.
What is Flair signal hyperintensity-multiple sclerosis?
After experiencing some minor numbness on my left side, I had 2 MRI on my head and brain. The report I received says, in part: “Several sulci of T2 and FLAIR hyperintensity within the white matter of both cerebral hemispheres” “Primary diferential considerations include sequela of chronic small-vessel ischemic disease.
What causes a patchy focus on the flair signal?
A patchy focus of increased T2 and FLAIR signal is seen in the leftward pons as well. These findings are non specific. Differential considerations include small vessel disease, gliosis, demyelinating pathology and Lyme Disease. Past history of MS 40 + years ago. At that time only one small patch was noted. Repeat Lymes testing – negative.
Where do you find Flair signal in MRI?
MRI w/wo contrast reads: Patchy, rounded and punctate foci of increased T2 and FLAIR signal in the periventricular and deep cortical white matter. A patchy focus of increased T2 and FLAIR signal is seen in the leftward pons as well. These findings are non specific.
How many T2 and Flair signal foci are there?
“There are at least 20 T2 and FLAIR hyperintense FOCI within the periventicular and subcortical white matter of both cerebral hemispheres”. Also, I had a recent ANA test and the results were: Positive/Titre 80/patteren speckled. Thanks. Of note I’ve suffered migraines for 15 years. I’m 50 years old.
