MRS is the abbreviation
for magnetic resonance spectroscopy. MRS is conducted
exactly the same as the MRI, but its capabilities go
further. While examining soft tissue to determine the
presence of prostate cancer, the MRS examines levels
of chemicals choline and citrate in the prostate. Since
many doctors have found that prostate cancer cells contain
more choline and citrate than normal tissues, MRS has
proven a useful tool to indicate which areas of the
prostate gland are more cancerous than others.
