Ultrasound cranium scans were performed on days 1\u20133 and 7 of life as per the study protocol. Baseline and clinical data of asphyxia, sepsis, and NEC were obtained. Images were acquired using a 4\u20138-MHz probe on a Sonosite M-turbo machine (Bothell, WA, USA). All statistical calculations were done using SPSS version 21.0 (SPSS Inc., Chicago, IL, USA) with the application of the Kolmogorov\u2013Smirnov test and the Mann\u2013Whitney test.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>During the study period, a total of 739 neonates were admitted. Of these, 73 neonates constituted the study group. Among the 73 patients, 33 were preterm neonates without comorbidities and 40 neonates had comorbidities such as perinatal asphyxia, sepsis, and NEC stage 2 and 3 (necrotizing enterocolitis). In the present study, the mean RI on day 3 of life was 0.76\u2009\u00b1\u20090.04 in neonates without comorbidities and 0.77\u2009\u00b1\u20090.04 in neonates with comorbidities, with a <jats:italic>p<\/jats:italic>-value of 0.247. On the 7th day of life, the mean RI was 0.82\u2009\u00b1\u20090.03 in both groups, with a <jats:italic>p<\/jats:italic>-value of
