Zhong Lab

 

 

The Zhong Lab is part of Magnetic Resonance Research Labs (MRRL) in the Department of Radiological Sciences within the David Geffen School of Medicine at UCLA. We aspire to further our understanding of human cardiovascular system and improve clinical diagnosis and treatment through development and translation of state-of-art technologies. Using Magnetic Resonance (MR) imaging as the primary modality, we develop advanced MR imaging techniques, image reconstruction algorithms, data analysis methods, deep learning networks and computational models to achieve our goal. We collaborate with physician researchers and industrial partners to steer our translational research, so that we better understand cardiovascular function and pathophysiology, and improve clinical diagnosis, treatment and monitoring of various clinical conditions including congenital heart diseases and acquired cardiovascular diseases. Our techniques also extend to applications of other organs such as the liver and skeletal muscle.
