Christodoulou Lab

The Christodoulou Laboratory develops and translates novel magnetic resonance imaging (MRI) techniques through innovations in MR physics, machine learning and image reconstruction. Our primary focus is on multidimensional quantitative imaging methods for the diagnosis, risk prediction and treatment monitoring of cardiovascular diseases and cancer.

Major Research Goal

Our long-term research goal is to enable comprehensive quantification of multiple MR biomarkers in a single, short “push-button” scan that simultaneously quantifies multiple biomarkers—for any organ and for a wide range of diseases. Our primary approach toward this goal, “MR Multitasking,” redesigns the quantitative MRI process to allow fast, accurate, and repeatable motion-resolved quantitative imaging—enabling non-ECG, free-breathing quantification of multiple tissue parameters at once, even in the heart and abdomen.
