The potential of 31P MRSI to detect prostate cancer in vivo at 7T was investigated in 12 patients with or suspected of having prostate cancer. The metabolites ratios PE/γATP, PE/tPLM and Pi/yATP showed significant difference between prostate cancer and normal prostate tissue. The performance of 31P MRSI to detect prostate cancer may improve further by increases in spatial resolution.
