Increasing the magnetic field strength to 7T can lead to improved quality of prostate imaging and 1 H-MRSI, and offers potential for use of new biomarkers in 31 P-MRSI. 7T abdominal imaging faces challenges including strong RF inhomogeneity, high SAR and increased sensitivity to off-resonance effects. Here we present the first steps towards a fully multiparametric MRI protocol for prostate at 7T, including high-resolution T2w, DWI and 1 H-MRSI. We show that excellent image quality in T2w and DWI with b-values up to 800 s/mm 2 and high quality spectra can be achieved in less than 60 minutes in 2 prostate cancer patients.
