Lead Sponsor:
University of Texas Southwestern Medical Center
Collaborating Sponsors:
National Institute for Biomedical Imaging and Bioengineering (NIBIB)
Conditions:
Fatty Liver
Eligibility:
All Genders
18-99 years
Brief Summary
The investigators plan to evaluate sensitivity and specificity of HP 13C-pyruvate as an imaging agent for detection of altered PDH flux in fatty liver.
Detailed Description
The investigators plan to determine whether nutritional state and fatty liver influence the production of \[13C\]bicarbonate from \[1-13C\]pyruvate via flux through the pyruvate dehydrogenase (PDH) re...

- Donated blood within the prior 4 weeks.
- Consume more than 10 grams of ethanol per day.
- Cirrhosis or any form of viral hepatitis.
- Prior documented hepatic reaction to drugs with a known hepatotoxicity profile such as isoniazid, methotrexate, phenytoin, propylthiouracil, valproate, etc.
