Clinical Translational Research Centers (CTRCs)

The best places to conduct your clinical research

At the CCTSI, we are focused on the unique needs of clinical investigators. We provide dedicated, research-only space for your clinical research. Our mission is disease agnostic, and we conduct many mechanistic studies with healthy controls.

The CTRC offers a variety of resources and services to help you with your research.

To make a request to use CTRC resources and services, just check the "CTRC" box in your IRB submission through the Human Subjects Research Portal.

If you are junior faculty, you may be eligible for a MicroGrant to cover the cost of CTRC services: remember to check the "Microgrants" box in your Human Subjects Research (HSR) Portal.

  • Metabolic meal planning and design, individualized for participant energy needs, food preferences, and study macro- and/or micro-nutrient targets
  • Metabolic meal preparation measurement, and dispensation
  • Dietary intake assessment – habitual and during protocol interventions
  • Hunger and satiety assessment 
  • Ad libitum feeding
  • Growth, body composition, and resting metabolic rate (RMR) measurements in children
  • Consultation on study design, American dietary norms, and ways to achieve specific dietary intervention targets
  • Protocol-specific dietary counseling and instruction
  • Design of palatable and acceptable foods/diets containing novel ingredients, combinations, or to mimic foreign specifications (eg. agrarian rural diet from a specific part of the world)

Cardiovascular BioImaging

The Cardiovascular BioImaging Core offers imaging techniques in vascular and cardiac ultrasound to provide a comprehensive assessment of cardiovascular health in children and adults:

  • Brachial artery endothelial function testing
  • Arterial stiffness
  • Intimal-medial thickness
  • Real-time three-dimensional (3D/4D) echo technology
  • Speckle tracking imaging that enables accurate measures regional and global cardiac function


Energy Balance and Assessment Core

We provide expertise for obesity- and nutrition-related research, including the measurement of components of energy balance (e.g., energy expenditure and intake) and for assessing consequences of alterations in energy balance (e.g., body composition, substrate oxidation), and bone structure (HRpQT).

NEW!!! High Resolution peripheral Quantitative Computed Tomography (HR-pQCT) is now available to obtain non-invasive 3D images at the distal tibia and distal radius of humans for clinical in vivo assessments of volumetric bone mineral density and parameters of bone quality (e.g., microarchitecture, geometry, porosity, and biomechanics). XtremeCT II HR-pQCT scanner images have a very small isotropic voxel size (60.7 μm) and very low radiation dose (≤5 μSv per scan/anatomical site) so the device can be used for studies performed in adult, adolescent, and pediatric populations.
