Abstract
Cranial sonography (CS) is the most commonly used tool for imaging the neonatal brain. Yet, little is known about inter-rater reliability and the effect of image quality on final interpretation. As part of a multi-center study, 1524 CS on 590 infants were interpreted for presence and severity(Papile grade) of intracranial hemorrhage (ICH) by 3 pediatric radiologists experienced in cranial sonography. Discrepancies among the 3 central readers were adjudicated and final interpretation reached by consensus. The quality of a subset of sonograms (1004) was assessed as good, poor but readable, and unreadable. Final interpretation by central readers was compared to that of local readers and congruence assessed by the Kappa statistic.
