Imaging blood vessels CARDIAC IMAGING
For more specific information on current research go Edward V. R. DiBella and Frederic Noo to then follow links to Research Interests Research is ongoing into improving acquisition and analysis of myocardial perfusion and viability images. Dynamic SPECT with 99mTc-teboroxime, dynamic PET imaging with ammonia and FDG, MRI functional and contrast injections and X-ray CT methods are some of the projects of interest. Dr. Ed DiBella in particular has projects in dynamic imaging with MRI and PET and the development of automated analysis methods for quantitative kinetic modeling of the data to obtain accurate physiological parameters.
Analytical heart model created for testing of X-ray CT reconstruction algorithms by Dr. Frederic Noo's group. This model is purely analytical so that discretization effects can be ignored. From left to right: coronal, saggital, and transaxial views. Micro CT Example microCT images of rodents demonstrating ~50 mm spatial resolution; clockwise from bottom left: heart and lungs, abdomen, rat spine, kidneys with IV contrast, and full body skeleton.
(Upper panels) Non-viable apical region shown with FDG-PET, left, and contrast enhanced MRI, right. (Lower panels) Non-viable inferoposterior region shown with FDG-PET, left, and contrast enhanced MRI, right. Arrows indicate regions of non-viability.
Example clinical images of dual-modality PET/CT imaging. The co-registered images in color demonstrate precise localization of tracer uptake.
