From the writeup:
“Other studies investigated the impact of either diet or exercise on the liver, not both,” said study author Elizabeth Parks, Professor of Nutrition and Exercise Physiology. “In addition, similar studies were just observational, but at Mizzou, we have technology for metabolic imaging that can give in-depth data on liver disease.”
The term “technology for metabolic imaging” just means they can look at any particular area or organ and watch change. That can mean they can do it with any organ, MRI, Magnetic resonance imaging (MRI) is a non-invasive medical imaging technique that uses radio waves and strong magnetic fields to create detailed pictures of the inside of the body: Nothing new there.
