Cardiovascular Computed Tomography Imaging

Our group has utilized the ability to image during the entire cardiac cycle to characterize regional differences in RV ventricular function in adult congenital heart disease patients and quantified the resolution limitation of CT coronary angiography.

Both ventricles can be visualized throughout the cardiac cycle

Cardiovascular Function via cineCT

Modern CT scanners provide the opportunity to acquire low-dose images throughout the cardiac cycle. This allows for visualization of cardiac function in either ventricle depending on the timing of contrast agent. We have combined this acquisition with a quantitative assessment tool (SQUEEZ) to characterize the regional heterogenity of function in adult congenital heart disease patients.

Coronary CT Angiography

Modern CT scanners can be utilized to non-invasively detect coronary artery disease via coronary artery angiography. However, despite engineering efforts to accelerate data acquisition, there are small motions that can occur during imaging. We have utilized computer simulations to evaluate trade-offs inherent to conventional scanners in terms of spatial resolution and the sensitivity to motion.
