CORE-320 Multicenter Trial Lab
The central theme of the CORE-320 Multicenter Trial Lab’s research is to support the Coronary Artery Evaluation Using 320-Row Multidetector CT Angiography (CORE 320) study, a multi-center multinational diagnostic study with the primary objective to evaluate the diagnostic accuracy of 320-MDCT for detecting coronary artery luminal stenosis and corresponding myocardial perfusion deficits in patients with suspected CAD compared with the reference standard of conventional coronary angiography and SPECT myocardial perfusion imaging.
Armin Arbab-Zadeh, MD, PhD, is an associate professor of medicine at the Johns Hopkins University School of Medicine and Director of Cardiac Computed Tomography in the Division of Cardiology at the Johns Hopkins Hospital in Baltimore.
Research Areas: coronary/cardiac imaging, coronary risk prediction, heart attack prevention, cardiac computed tomography, coronary circulation and disease
The J. Webster Stayman Lab studies both emission tomography and transmission tomography (CT, tomosynthesis and cone-beam CT). Our research activities relate to 3-D reconstruction, including model-based statistical / iterative reconstruction, regularization methods and modeling of imaging systems. We are developing a generalized framework for penalized likelihood (PL) reconstruction combining statistical models of noise and image formation with incorporation of prior information, including patient-specific prior images, atlases and models of components / devices known to be in the field of view. Our research includes algorithm development and physical experimentation for imaging system design and optimization.
The Lima Lab’s research is concentrated on the development and application of imaging and technology to address scientific and clinical problems involving the heart and vascular system.
Specifically, our research is focused on developing magnetic resonance imaging (MRI) contrast techniques to investigate microvascular function in patients and experimental animals with myocardial infarction; functional reserve secondary to dobutamine stimulation and myocardial viability assessed by sodium imaging; and cardiac MRI and computed tomography (CT) program development of techniques to characterize atherosclerosis in humans with cardiovascular or cerebrovascular disease.
Current projects include:
• The Coronary Artery Risk Development in Young Adults (CARDIA) Study
• The MESA (Multi-Ethnic Study of Atherosclerosis) Study
• The Coronary Artery Evaluation using 64-row Multidetector Computed Tomography Angiography (CORE64) Study
