Yi Wang, Ph.D., is the Director of the Magnetic Resonance Imaging Research Institute (MRIRI). He has invented multiple MRI technologies of great importance to the clinical and scientific communities, including, a) quantitative susceptibility mapping (QSM), which has led to a new MRI discipline for studying tissue magnetism, b) the stepping table platform with multiple local coils for large field of view (FOV) imaging, and c) quantitative transport mapping (QTM).
Major research interests in Professor Wang’s lab involve applying and developing data science, machine learning, optimization, physics, and statistical inference techniques for medical imaging acquisition and analysis. These include increasing imaging speed, reducing image artifacts, and generating novel image contrasts/biomarkers using computer vision and signal processing strategies. The lab seeks to formulate medical imaging problems for disease diagnosis and therapy delivery, as inverse problems from acquired signals to underlying pathogeneses based on biophysics. The lab works closely with clinicians to study neurological diseases such as multiple sclerosis (MS), Parkinson’s disease (PD), Alzheimer’s disease (AD), stroke, cancer in various organs, and liver and heart diseases. The inverse problems are often poorly conditioned and involve noisy incomplete data, resulting in reconstructed images with errors or artifacts commonly encountered in computer vision. The lab has developed the Bayesian statistical inference approach to removing image artifacts in MRI using prior knowledge established in biomedicine, or acquired from multiple imaging modalities, including immunohistochemical staining and optical imaging.
The lab’s work is exemplified by the following:
QSM to solve the field-to-susceptibility inverse problem using the Bayesian approach. Tissue susceptibility reflects molecular electron cloud properties, and QSM enables its precise quantitative study. QSM has become a very active field of studying tissue magnetism for applications in neurodegeneration, inflammation, oxygen consumption, hemorrhage, liver, osteoporosis, atherosclerosis and drug delivery. QSM is increasingly used in clinical practice, particularly in precision targeting for deep brain stimulation, precision monitoring of chronic active hemorrhages and inflammation, precision medication for iron chelation therapy, and precision diagnosis and gadolinium-free imaging for multiple sclerosis.
QTM to solve the inverse problem from imaging to tissue perfusion quantification. The lab develops fast dynamic imaging (4D) to capture tracer (drugs, contrast agents, and spin labels) transport in tissue using super resolution, sparsity, and deep learning techniques. Perfusion parameters affect imaging through convolution in space time according to transport equation of mass and momentum flux laws. The lab develops QTM to deconvolve 4D time-resolved imaging for perfusion quantification. QTM enables precise measurement of blood flow in tissue and helps with precise delivery of therapeutic drugs, cryotherapy, and tissue ablation.
Lesion segmentation from acquired images to enable automated precise measurements and analyses of disease burden. The lab employs various image segmentation techniques including image feature-based approaches and deep neural network-based approaches.
