To learn more about current Technology Researcher & Development (TR&D) projects, to request the formation of a Collaborative Project (CP) or Service Project (SP), or to find contact information for the principal investigators of each project, go to PET-RTRC Projects.


The PET-RTRC offers a variety of novel radiopharmaceuticals under the Collaborative Projects (CP) and Service Projects (SP) mechanisms. These include specific agents 11C-TZ3321 (S1P1) and 64Cu-DOTA-ECL1i, which target inflammation, and novel 68Ga based imaging agents that target ROS-mediated Oxidative Stress.

If you have any questions or to learn more about how these agents can be used to further your research goals, email Michelle Hoelscher.

All Radiopharmaceuticals and Radiochemicals listed below are prepared in-house using the MIR Cyclotron Facility & Nuclear Pharmacy. This list is not comprehensive, but does highlight the compounds available. For additional information on any of the products listed below, email Michael Nickels, PhD.

Quantitative Imaging & Informatics Resource (QI2R)

The QI2R was established to:

  • ensure standardized evaluation of radiotracer performance
  • facilitate the movement and management of data throughout the PET-RTRC

The QI2R has two primary functions:

  • quantitative image analysis of PET-RTRC image datasets
  • development and management of informatics pipelines

The QI2R will provide guidance and expertise in quantitative imaging to be employed by TR&Ds.  In doing so, the QI2R will promote standardized/unified image analytics across PET-RTRC activities and promote training of Center members.

The QI2R will develop and implement advanced quantitative imaging pipelines to characterize radiotracer performance. 

To facilitate the movement and management of data throughout the PET-RTRC, the QI2R developed the co-clinical database (CCDB).  The CCDB is built on XNAT, a widely used open-source imaging informatics platform.  XNAT is a web-based software platform designed to facilitate common management and productivity tasks for imaging and associated data.  A fine-grained access control system ensures that users are restricted to accessing only authorized data.  XNAT also includes a web services API for programmatic access and a plugin architecture for extending XNAT’s core capabilities. For QI2R, data contributors will upload Center-related data and metadata to the CCDB using a secure web application. Data will be organized in study-specific projects that provide access to authorized personnel. 

For more information, email Michelle Hoelscher

Technology Training & Dissemination

Training is available for PET radiochemists and radiopharmacists to synthesize radiotracers produced by the PET-RTRC and scientists who use this technology. We provide opportunities for interested researchers, such as basic scientists with training in preclinical imaging using PET radiotracers and clinician scientists in the design and conduct of human research studies using PET as an imaging modality.

  • Individualized hands-on training is available
  • 2-3 month lead time is needed

Facility Support

In its effort to advance precision imaging, the PET-RTRC regularly utilizes the resources and services of three of MIR’s leading-edge facilities.

The CCIR assists PET-RTRC investigators and their collaborators in the basic and translational science imaging research studies. The facility is linked directly to the Cyclotron Facility & Nuclear Pharmacy by a pneumatic tube system for purposes of immediate unit-dose delivery of radiopharmaceuticals.

Learn more about the CCIR.

The Cyclotron Facility & Nuclear Pharmacy is instrumental to the PET-RTRC’s core mission of developing and disseminating novel PET radiotracers used in preclinical and human imaging studies. The facility’s director is Training and Dissemination co-leader Michael Nickels, PhD.

Learn more about the Cyclotron Facility & Nuclear Pharmacy.

The PET-RTRC utilizes an array of services from the Preclinical Imaging Facility, including multi-modality PET/CT imaging, simultaneous PET/MR imaging and Bioluminescence imaging of radioactive materials. The facility is directed by QI2R co-leaders Richard Laforest, PhD and Kooresh Shoghi, PhD.
