Accurate identification of the thalamus sub-structures is therefore important for localization of specific nuclei and for the understanding of brain function. However, sub-structures of the thalamus are so small and have intermediate signal characteristics between grey/white matter it has been difficult to identify them with conventional MR imaging technique. In this work, in-vivo T₁ value at 7T are measured using fast T₁ mapping technique in less than 2 min and optimized inversion time to generate optimal contrast from the thalamus. The optimized results reveal markedly improved anatomical detail of the sub-structures of the thalamus, including their detailed locations.
