Clinical MR Spectroscopy of Brain Metastases at 1,5T and 3T.

In Vivo Proton MR Spectroscopy of Brain Metastases Obtained at 1,5T and 3T.

Increasing magnetic field is known to give improvements in signal-to-noise-ratio (SNR) and spectral resolution. To investigate this, spectra from different subjects were examined using two clinical MR instruments operating at 1.5T and 3T respectively.

Inclusion Criteria:

• brain metastases
