Dr. Dara Kraitchman is a Professor in the Johns Hopkins Medicine Department of Radiology and Radiological Science. Her research focuses on non-invasive imaging and minimally invasive treatment of cardiovascular disease. Dr. Kraitchman serves as the Cardiovascular Interventional Section Head within the department. Dr. Kraitchman is also the Director of the Center for Image-Guided Animal Therapy (CIGAT), which provides state-of-the-art imaging and minimally invasive diagnostic and therapeutic options for pets as well as veterinary clinical trials.

The Kraitchman lab developed the first technique to provide radiopaque labeling of stem cells for x-ray fluoroscopic delivery and CT imaging of stem cell persistence for cardiac and peripheral arterial disease applications.

Dr. Kraitchman received her undergraduate degree in electrical engineering from Carnegie Mellon University. She earned her M.S.E. and Ph.D. in bioengineering from University of Pennsylvania. She also completed her V.M.D. in veterinary medicine from University of Pennsylvania. Dr. Kraitchman joined the Johns Hopkins faculty in 1996.

She is a Fellow of the American College of Cardiology and International Society for Magnetic Resonance in Medicine and a Distinguished Investigator in the Academy of Radiology.

Research Summary

Dr. Kraitchman's research interests are concentrated on non-invasive imaging and minimally invasive treatment of cardiovascular disease and cancer. She has been actively involved in developing new methods to image myocardial function and perfusion using MRI. Current research interests are aimed at determining the optimal timing and method of administration of stem cells for cardiac regeneration using non-invasive MR fluoroscopic delivery and imaging. MRI, X-ray, and radiolabeling techniques include novel microencapsulation techniques to label stem cells to determine the location, quantity and biodistribution of stem cells after delivery as well as to noninvasively determine the efficacy of these therapies in acute myocardial infarction, peripheral arterial disease, and non-ischemic dilated cardiomyopathy.  Microencapsulation techniques are also used for enhanced stem cell engraftment.

She is also focused on the development of new animal models of human disease for noninvasive imaging studies and the development of promising new therapies in clinical trials for companion animals.  Novel embolics are being studied for the treatment of brain, lung, and bone cancer in pets with spontaneously occurring disease. Recent veterinary clinical trials are focusing on the combination of immunotherapy with cryoablation for the treatment of bone cancer. In addition, low-cost devices for third world countries are being repurposed for the veterinary market to enhance therapies for pets.
