Many disorders such as multiple sclerosis or focal
cortical dysplasia (FCD) require the use of MRI to
precisely delineate size limited lesions. Optimizing
MRI sequences to enhance the contrast between healthy
and pathological tissues is necessary. In addition,
improving brain images postprocessing algorithms of
pathological subjects where usual assumptions are void
is an important task. For this purpose, it is of primary
interest to develop test objects able to mimic the
aspect of certain brain lesions. This will allow the
optimization for both MRI sequences and postprocessing
algorithms. In this work, we present a useful test
object for sequences optimization.
