Definition
MR spectroscopy is a promising development in the radiological evaluation of possible prostate malignancy. The MR spectroscopic evaluation is mainly based on the choline peak elevation and choline-creatinine ratios.
Choline/creatine to citrate ratios:
> 0.5: suspicious
> 0.8: very suspicious
> 2: abnormal
Additionally, the peak heights of citrate and choline can be compared visually2.
The addition of MR spectroscopic data to the conventional MRI has improved detection of prostate cancer and has also improved tumor volume detection, and staging capabilities of MRI.
