In 7T breast MRI, the use of local transmit coils causes an inhomogeneous B1+ field, decaying towards the pectoral muscle. This leads to differences in image contrast throughout the breasts and in dynamic contrast enhanced (DCE) MR images it has a direct influence on the enhancement kinetic curves. Therefore a correction is necessary. We used B1+ simulations to generate a template to correct the images, because the dynamic range of measured B1+ maps is often insufficient. We validated the template on eleven volunteers. T1-maps were calculated using the generic template as a first step of correcting the DCE images.
