As an effective but poorly understood treatment for the prevalent bipolar disorder, studies focused on investigating the cerebral distribution of lithium are of important clinical interest. Here, we report our preliminary results obtained from 5 euthymic bipolar patients using 7Li MRI at 7T. Using a 3D SSFP sequence with ultra-short TE and Twisted Projection Imaging k-space sampling, we can confirm the heterogeneity of lithium brain distribution, as demonstrated by the individual and average concentration values in seven large regions-of-interest.
