Abstract
Objective:To compare information obtained from preterm magnetic resonance imaging (MRI; 31–34 weeks) brain scan to that done at term equivalent age.Study design:Prospective observational study of premature infants with evidence or suspicion of parenchymal brain injury on cranial ultrasound. Brain injury on two scans scored using a scoring system and analyzed.Results:Fourteen infants with a median (range) gestation at birth of 28 (25–29) weeks and birth weight of 1254 (680–1557) grams were studied. There was a strong correlation between the brain injury scores for the two scans (Spearman ρ=0.87, P=0.001) with excellent agreement between two radiologists (interclass correlation coefficient 0.9–0.94). There was also a high level of agreement between the preterm and term MRI two scores (Intraclass correlation coefficient, 0.79 (0.53–0.94)).Conclusions:Preterm MRI is a feasible option for the assessment of preterm brain injury and analysis of data obtained from scan at preterm age is comparable to that obtained at term equivalent age.
