Vascular Imaging

Vascular imaging example.

Cardiovascular disease represents a major clinical problem both here in the United States and in the rest of the world. Early detection is challenging because the disease progresses slowly and is, in many cases, asymptomatic. The goal of this research is to use ultrasound elastography to detect disease in the carotid artery of patients that are at risk of developing cardiovascular disease. Specifically, we detect vascular aging in the HIV+ population, detect subclinical atherosclerosis, and evaluate the efficacy of novel genetic and pharmacological therapies.
