Background: The correlation between IQ scores and brain structures is still unclear. The brain volume may be one of the neurophysiological indicators for assessment of intelligence in children. This study aims to find the correlation between IQ score levels in Egyptian children and the MRI volumetric measurements of brain structures in aberrantly normal conventional MRI. Methods: A retrospective study included fifty-one children with normal conventional brain MRI studies were referred from Children and Maternity Hospital, Minya University in the duration from October 2018 to December 2019. Their ages were ranged from 2 to 14 years. Inclusion criteria: child has delayed speech, hyperactivity or learning disabilities in preschool age with aberrantly normal conventional MRI examination, exclusion criteria: Children with an abnormal MRI brain examination or have a contraindication for MRI techniques were excluded from this study. All children presented with delayed speech or with history of delayed speech as early clinical sign of delayed milestone They suspected to convectional MRI and volumetric MRI examination & IQ test (Stanford-Binet intelligence scales: fifth edition). Volumetric MRI assessed by automated online processing using (VolBrian.com) pipeline. Result: 51 subjects were included in this study for an average age of 7.8±3.1year, the average IQ level was 64.69±13.9, with an average total brain volume 1227.96±204.26cm3. Despite positive correlation between IQ scores and brain radiographic measures, only total brain volume (p value = 0.024), intracranial cavity (p value = 0.041) and grey matter volume (p value = 0.009) had a statistically significant correlation with IQ levels. Additionally, males had a significant correlation between IQ scores and total brain volume (p value = 0.043) as well as grey matter volume (p value=0.012). Conclusion: Total brain volume is directly and significantly correlated with IQ scores in Egyptian children, especially in males. Further studies with more robust design are needed.
