Abstract

See full text

The present disclosure provides a method for optimizing T1-weighted magnetic resonance imaging of infant brains. Firstly, T1 and PD maps of infant brains at 0-12 months old are collected to obtain average T1 and PD values of WM and GM of the infant brains, and infants are classified into three age groups according to the characteristics of WM and GM T1 values of the infant brains. Then, the theoretical signal strength of the WM and GM of the infant brains generated from a 3D T1-weighted imaging sequence is calculated through Bloch simulation, and a theoretical optimal TI scheme of each group is determined according to the simulated WM/GM contrast characteristics under different TIs. Finally, the theoretical optimal TI scheme is applied to a target infant brain according to the designated age group for 3D T1-weighted magnetic resonance imaging.
