Magnetic resonance imaging is used in oncology in particular for tumor staging, planning of surgery and radiation therapy, and monitoring of tumor response and early detection of recurrence. For all applications high field MRI can be advantageous, because the spatial resolution of the MR images is increasing with field strength, and thus smaller lesions become detectable. Furthermore, functional imaging techniques benefit from the higher field strength, which are used as early indicators for therapy response or tumor recurrence before morphological changes are visible. Several technical limitations such as the increased specific absorption rates (SAR), the limited B1 homogeneity of the transmit coils or the increased image distortion due to susceptibility differences make high field MRI of tumors challenging. Nevertheless, high resolution morphological and functional images of brain tumors have been acquired showing the internal tumor structure, the presence of neo-angiogenic vessels, and the functional changes of the tumor tissue.
