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.
