Atherosclerosis Imaging Research Program

The University of Wisconsin Atherosclerosis Imaging Research Program (UW AIRP) is a core ultrasound reading and training laboratory for clinical and epidemiological research studies that use ultrasound and other physiologic research tools as surrogates for atherosclerosis, arterial injury, and cardiovascular disease risk:

  • Carotid artery intima-media thickness and grayscale analysis
  • Carotid artery plaque detection, quantification, and grayscale analysis
  • Brachial artery reactivity testing and grayscale analysis
  • Arterial stiffness (by tonometry and ultrasound)
  • Assessment of cardiac structure, function, and coronary blood flow (by echocardiography)

We also perform electrocardiography-based research including 12-lead electrocardiograms, treadmill stress testing, Holter monitoring, and assessment of heart rate variability as well as coronary artery calcium scoring using cardiac computed tomography.

The UW AIRP is proud to serve as the Carotid Ultrasound Reading Center for the NHLBI Multi-Ethnic Study of Atherosclerosis (MESA), the Fragile Families Cardiovascular Health Follow Up Study, and several other NIH-funded research studies. We also are the BART Reading Center for the NHLBI HIV-CVD Collaborative and several other studies.
