Population Variability of Susceptibility-Induced B0 Field in Bilateral Breast MRI

Seung-Kyun Lee¹, Ileana Hancu¹

Susceptibility-induced B0 field in bilateral breast was calculated in thirteen healthy volunteers based on segmented anatomical images at 3 T. For each volunteer, nine axial B0 maps were fitted with spherical harmonics up to the third order, and population variability was investigated. Common features in the susceptibility-induced B0 gradient were identified and the effectiveness of higher order shim was evaluated.
