About ABT

ABT Molecular Imaging, Inc. was founded by Ron and Lynda Nutt in 2006 and is located in Knoxville, Tennessee where clinical PET was developed beginning in the early 1980’s. Our Vision is expanding access to PET throughout the world.

This vision will be realized through the “Dose on Demand” Biomarker Generator by providing researchers and clinicians on-demand access to PET biomarkers. 


 The BG-75 Biomarker Generator

 - Is a small, simple, cost effective mini-cyclotron isotope generator with integrated microchemistry and automated quality control to deliver PET biomarkers at the push of a button. 

- Functions as a self-contained PET biomarker lab that fits in a single 30 square-meter room and can be easily integrated into an existing clinical or research setting, adjacent to clinical or research PET imaging equipment without the need for highly specialized staff.


-  The small size and integrated components take the place of a large, conventional system requiring a 371.61 square meter facility, with fully equipped hot labs, quality control equipment, and significant staffing for operation. The size, cost and complexity difference provides a much lower barrier to entry to have access to radioisotopes on demand, and enables the expansion of advanced radiochemistry research in clinical and pre-clinical Molecular Imaging.


Broader access to PET biomarkers will aid in the development of new biomarker technology, advance PET imaging and contribute to realizing the potential of molecular imaging’s contribution towards personalized medicine. ABT has installed Biomarker Generators in many parts of the world, including USA, Western and Eastern Europe, Russia and Latin America. We provide global installation, service and applications support from our Manufacturing & Research Center in Knoxville TN, very close to where clinical PET was developed over the past 25 years at CTI Molecular Imaging, which Dr. Nutt co-founded.


With a combined 150 years of PET experience, ABT’s team has a long history in PET imaging. Meet our talented and experienced team members who are working to expand the utility and presence of the BG-75 Biomarker Generator worldwide.
