Another NIBIB-funded researcher is trying to solve this problem from a different angle. He is developing a motion correction system that could greatly improve image quality for MR exams.

This improvement could reduce cost since less repeat MR exams will have to take place due to poor quality as well as make MRI a viable option for many patients who are unable to remain still for the exam and reduce the amount of anesthesia used for MR exams.

Determining the aggressiveness of a tumor Traditional MRI, unlike PET or SPECT, cannot measure metabolic rates. However, researchers funded by NIBIB have discovered a way to inject specialized compounds hyperpolarized carbon 13 into prostate cancer patients to measure the metabolic rate of a tumor.

Monitoring disease progression can improve risk prediction, which is critical for prostate cancer patients who often adopt a wait and watch approach.
