    Background: Hypoxic-ischemic encephalopathy (HIE) is a serious condition that results of critical failure of the intrapartum gas exchange and may lead to a signifi cant damage in the central nervous system.

    Objective: to elucidate the role of brain magnetic resonance imaging (MRI) versus Proton magnetic resonance spectroscopy (1H-MRS) in the diagnosis and evaluating the severity of HIE in full-term Egyptian neonates

    Design: 49-months observational controlled study.

    Setting: Pediatric neurology and Radiology Departments, Alexandria University Hospital       

     Patients and Methods: Thirty full-term neonates in the fi rst two weeks with HIE (Sarnat staging) were included (18 males and 12 females), with exclusion of those with congenital brain malformation and/ or
    perinatal infection in addition to 15 age- and sex- matched healthy controls. All patients and controls were
    examined with brain MRI and 1H-MRS.

    Results: In neonates with HIE, the percent of agreement between clinical staging, and MRI grading
    was 66.67 while it was 76.67 regarding 1H-MRS grading. The sensitivity for MRI was 66.67%, specifi city
    was 75%, accuracy was 77.78%, PPV was 80% and NPV was 75%. Meanwhile, the sensitivity for 1H-MRS
    was 92%, specifi city was 75%, accuracy was 84.44%, PPV was 82.14% and NPV was 88.24%.

    Conclusion: 1H-MRS detected more percent of agreement, true positive and less false negative cases
    than MRI. Despite the equal specifi city between them, still 1H-MRS got more sensitivity, accuracy, PPV
    and NPV than MRI i.e. when we have to choose early and single investigation it is recommended to choose
