Cerebral perfusion in subjects with HIE after
hypothermia have not been well described. The purpose of
this study was to assess perfusion on ASL and compare to
conventional MRI in the second week of life. CBF values
were compared to normals reported in the literature.
Subjects with qualitative basal ganglia injury on
conventional MR had lower CBF. Relative hyperemia in
deep gray matter with no corresponding qualitative
abnormality may be related to timing of injury
evolution. CBF can quantified by ASL in hypothermia
treated infants in the second week of life. Longitudinal
studies are needed to evaluate the progression of
hyperperfusion.
