While increased sensitivity provided by high magnetic fields can benefit volumetric whole-brain echo-planar spectroscopic imaging (3D EPSI) in several ways, the gain in measurement repeatability and reproducibility compared to EPSI performed at lower fields, i.e. 1.5T, has not been thoroughly investigated. Here, a test/retest study is presented for 3D EPSI of normal human brain at 4 T focusing on repeatability.
