This work describes our initial experience in performing in vivo MRS of the human breast at very high field. Using a unilateral transmit/receive coil design and single-voxel localized spectroscopy, a total choline resonance was detected and quantified in 4/5 normal subjects, and a taurine resonance was observed in 2/5 same subjects. Additionally, we report measurements of respiration-induced frequency variations and relaxation rates for water and lipid resonances. These preliminary data show that 7 Tesla breast MRS is feasible and may lead to improved spectroscopic characterization of breast lesions.
