A postprocessing brain MRI allowed obtaining automatically both volumetry
and T1 relaxometry values. It helps radiologists to
quantify brain abnormalities undetected in brain MRI in more than 80% of the initial exploration of children
with focal epilepsy of unknown cause.
Sagittal, axial
and coronal views (line A, B and C) of the MP2RAGE sequence with the
postprocessing morphometric analysis results of a 6 years girl having left
focal epilepsia. UNI column is a highly contrasted T1 image. T1 relaxometry map
is the second column. Morphobox column represents the brain segmentation
obtained. A Volumetry and T1 relaxometry Z-score maps are also provided for a
visual analysis. We noticed a decreased T1 relaxometry values in the left
cortical occipital grey matter.
