Cardiovascular & Thoracic Imaging

Chief of Cardiovascular and Thoracic Imaging in the Department of Radiology

Assistant Professor of Radiology (Cardiovascular and Thoracic Imaging) 

Bio

My research and clinical interests include medical imaging, cardiovascular disease diagnosis and treatment, lung cancer, fluid mechanics, and computer science. As a cardiothoracic radiologist, I am interested in applying advanced imaging techniques, primarily cardiovascular and pulmonary magnetic resonance imaging (MRI), in diseases, cohorts, and clinical scenarios where these techniques have not been previously applied.

Assistant Professor of Radiology (Basic and Translational Radiology Research)

Bio

My expertise intersects between computer science, medical imaging and applied fluid dynamics. I have 12+ years of experience in medical image analysis research and development in both academia and industry. Recently, I have been focusing my research on cardiovascular hemodynamics, where I employ my technical background in medical image analysis, cardiovascular 4D flow MRI and fluid dynamics to develop methods to improve diagnosis and treatment of heart disease using the state-of-the-art 4D Flow MRI technology. In particular,I have developed methods to utilize 4D Flow MRI for advanced visualization and quantification of 3D time-resolved intra-cardiac blood flow patterns and energetics. For further details, visit my lab's website or the Northwestern CVMRI Group page.

Knight Family Professor of Cardiac Imaging

Professor of Radiology (Basic and Translational Radiology Research) and McCormick School of Engineering

Bio

I am the Director of CV Imaging at the Center for Translational Imaging. My research focuses on development of rapid MRI acquisition and reconstruction methods to address unmet needs in cardiovascular medicine. Our lab focuses on breaking new grounds in cardiovascular MRI by developing innovative pulse sequences and reconstruction methods to address unmet clinical needs in cardiovascular medicine. Building upon active collaboration with radiology and cardiology colleagues, our research activities span from imaging technology development to clinical translation in cardiovascular medicine.

Currently, ongoing projects include:

1. Role of diffuse LV fibrosis in patients with atrial fibrillation
2. Real-time CMR for diagnosing CAD
3. Rapid pediatric CMR without requiring contrast agent or anesthesia
4. Advanced CMR assessment of left atrial hemodynamic disorders in atrial fibrillation
5. Wideband CMR for predicting pre-implant right heart failure in LVAD candidates
6. Wideband CMR for imaging patients with ICDs

Research Associate Professor of Radiology (Basic and Translational Radiology Research)

Bio

I have a broad background in quantitative cardiovascular imaging, with specific training and expertise in coronary artery MRI. My research is focusing of identify subclinical coronary artery disease (CAD) in patients suffering type 2 diabetes mellitus (T2DM). In addition, I am also interested in evaluating regional myocardial changes in patients with various clinical or subclinical cardiovascular diseases. Recently, I am developing research projects for evaluating cardiovascular responses in treating cancers, immunological and neurodegenerative disorders, such as breast cancer, systemic lupus erythematosus (SLE), Alzheimer’s disease (AD) and Parkinson’s disease (PD).​ For details and images, visit the Northwestern CVMRI Group page.

Vice Chair for Research, Department of Radiology

Lester B. and Frances T. Knight Professor of Cardiac Imaging

Professor of Radiology (Basic and Translational Radiology Research)/McCormick School of Engineering

Bio

I am currently the Vice Chair of Research for the Department of Radiology. I have established a strong interdisciplinary research consortium. My research has had a major impact on the diagnosis and management of heart disease and stroke including 1) development of novel imaging techniques for the assessment of cardiac structure, function and hemodynamics, and 2) discovery of mechanisms underlying cardiovascular diseases development and cryptogenic stroke (aortic hemodynamics as a mechanism in the development of BAV aortopathy; retrograde embolization from aortic plaques and left atrial flow dynamics in atrial fibrillation as risk factors for stroke). I am internationally recognized as the pioneer of 4D flow MRI and work in this area has advanced the understanding of cardiovascular disease processes as well as enhanced patient care. I have created a highly successful and inseminating training environment in MRI technique development and translational imaging research.

Research Assistant Professor of Radiology

Bio

With a mechanical engineering Ph.D. background, my expertise lies in flow imaging and analysis for experimental fluid dynamics investigation. My key research interest is developing a multimodality quantitative cardiovascular flow assessment technique to understand cardiovascular fluid dynamics better and improve the diagnosis of cardiovascular diseases. My current work focuses on combining 4D flow MRI, echocardiography, and in-vitro flow modeling to understand valvular heart diseases better.
