The BioImaging Resource Core (BRC), part of Wake Forest University School of Medicine’s Claude Pepper Older Americans Independence Center (OAIC), provides leadership, scientific expertise and instrumental support in quantitative imaging techniques, including MRI, CT, DXA, PET and HR-pQCT.
The BRC leads the development and implementation of imaging techniques and protocols to quantify and characterize body composition, particularly skeletal muscle and total, regional and organ-specific adipose tissue, as well as to obtain non-invasive measures of vascular and neuromuscular function.
The core also supports a large image repository to facilitate cross-study comparisons and exploratory analyses of established imaging outcomes as well as the rapid development and validation of new imaging phenotypes.
Highlighted Core Supported Research
Image Repository Harmonization
- Administrative Supplement award (P30 AG021332-17S1) to modernize, harmonize and integrate the imaging data workflows of the WF OAIC and WF Alzheimer’s Disease Research Center (ADRC) to increase access to imaging data and facilitate the repurposing of images for future theme-relevant research.
Radiologic Aging Phenotype Identification (RAPID) Working Group
- Led by Dr. Leon Lenchik and Dr. Da Ma, this working group brings together the imaging and fluid biomarker cores of the WF OAIC and ADRC to support development and integration of body and brain imaging phenotypes in older adults.
