Researchers at Massachusetts General Hospital in Boston, US have developed an imaging technique to find a tumour located in the prostate.

Researchers have used magnetic resonance spectroscopy (MRS) to analyse the chemical composition rather than the structure of tissues to better locate prostrate tumours.

MRS detects tumours that cannot be found with other imaging approaches and may provide information that can help determine the best course of treatment, the study said.

Researchers identified 36 critical metabolites that were active in prostate tumours that differed from a healthy prostate, Reuters reports.

With the help of the software, researchers scanned prostate glands that had been removed and were later dissected in the lab.
