Antenatal and mostly post-natal periods are crucial for brain development, characterized by volume increase, brain maturation, neuronal proliferation, neural migration, and myelination. Head circumference is a reliable clinical assessment of brain volume, correlated with neurodevelopmental outcomes (psychomotor and cognitive development). Particularly in young children, it is a fast and inexpensive tool for brain growth follow-up. Complementarily, brain MRI is becoming more frequently used as a first-line examination for suspected brain development abnormality. In this work, we evaluate the potential of an automated MP2RAGE-based brain volumetry method to objectively support radiologists to better assess brain physiological and pathological cerebral growth.
