The introduction of high-field magnetic resonance imaging (MRI) into neuro-oncological imaging allows improved visualization of tumor structures even in the field of T1 and T2-weighted imaging. Susceptibility-weighted imaging (SWI) and time of flight (TOF) angiography in particular greatly benefit from the high field strength. The visualization of tumor vasculature in MRI, which was made possible by high-field technology can potentially be applied to monitoring antiangiogenic therapy. Cerebral metastases can potentially be discovered earlier using high-field technology. Furthermore, high-field technology permits the use of new technologies, such as sodium imaging, which is expected to provide new information in the field of tumor pathophysiology.
