Motivation: Brain T2* values can provide information about tissue specific maturation, and can also provide knowledge important for optimising echo times for fMRI acquisition.
Goal(s): To characterise tissue specific T2* values in the neonatal brain at 7T.
Approach: Whole brain T2* maps from 14 neonates were generated using a 3D multi-echo acquisition.
Results: Median T2* values were: cortical grey matter: 58 ms, deep grey matter: 70 ms and white matter: 86 ms. Values differ markedly from those described in adults and measured at standard field strengths.
Impact: We describe tissue-specific T2* values in the neonatal brain at 7T, which may provide new information about brain development in health and disease, and provide a basis for optimising fMRI sequences for neonates at 7T.
