Figures
- Fig 1.
Coronal reformatted views of 3D-FLAIR with (A) and without (B) CS, showing a juxtacortical lesion involving the right frontal superior gyrus (arrows) in a 50-year-old female patient with relapsing-remitting MS. Note the similar delineation of the gray-white matter junction between conventional and CS FLAIR.
- Fig 2.
Axial reformatted views of 3D-FLAIR with (A) and without (B) CS, showing a periventricular MS lesion also involving the left middle cerebellar peduncle (arrows) in a 31-year-old female patient with relapsing-remitting MS. Note the excellent and similar suppression of CSF obtained with both sequences.
- Fig 3.
Axial and coronal reformatted views of 3D-FLAIR with (A and C) and without (B and D) CS, showing an MS lesion involving the cisternal and canalicular portions of the left optic nerve (arrows) in a 48-year-old female patient with relapsing-remitting MS.
- Fig 4.
Automatic postprocessing performed with Quantib Brain 1.2 software allowing the assessment of MS lesion volumes using CS (A) and conventional FLAIR (B). With such a quantitative approach, FLAIR hyperintensities of the whole brain were taken into account. There was no significant difference between both FLAIR acquisitions in the total MS lesion volume (P = .63) and number (0.15).
