Predictive value of 1H MRS in hypoxic encephalopathy. Two pairs of studies are presented, and in each case MRS was performed at the neonatologist's request after a neurological opinion suggested severe hypoxic brain injury with very guarded prognosis: Patient 1, in whom the neurological outcome was excellent, was a comatose infant examined on day 1 and again on day 4 (not shown). Patient 2, in whom neurological outcome was poor, was examined in coma on day 5 and again on day 35 (not shown).
