Cardiovascular Magnetic Resonance Imaging

Our group has developed real-time cardiovascular magnetic resonance (CMR) imaging approaches as well as self-gating strategies. More details on these efforts can be found below.

Real-time MRI of a patient with sinus rhythm followed by an arrhythmia

Self-gating of a patient with trigeminy allows visualization of three contractions

Real-Time Cardiac MRI


We have developed techniques to perform real-time cardiac magentic resonance imaging in normal subjects, clinical patients, and translational animal studies. Our techniques overcome the conventional sampling limitations of MRI systems and allow us to clearly visualize irregular heart beats (arrhythmias) and measure advanced estimates of cardiovascular function such as PV loops and end-systolic pressure-volume relations (ESPVR).

Self-gated MR Imaging


Conventional cardiac MR imaging techniques typically combine data acquired several heartbeats to increase image spatial and temporal resolution. This can prove challenging in patients with irregular heart rhtyhms or changing hemodynamics. We have developed techniques which sort acquired data based on physiologic information and result in high resolution imaging of arrhtymic beats
