In this study we show the feasibility of 31P MRSI acquisition from a lung carcinoma tumor in a patient using a 31P whole body birdcage coil at 7T. We showed that even without B0 shimming, 31P spectra could be aligned and averaged to differentiate several metabolites, related to membrane metabolism, in the lung tumor. 31P MRSI has great potential for the detection of therapy response in lung tumor cancer, as often the tumor is still relatively large to obtain sufficient spectral signal.
