According to van Wezel et al.
Grade 0: normal echogenicity of the
periventricular white matter ( less than that
of the choroid plexus)
Grade 1: moderately increased echogenicity
of the periventricular white matter, the
affected region being almost as bright or as
bright as the choroid plexus .
Grade 2: seriously increased echogenicity,
the affected region being obviously brighter
than the choroid plexus ....
