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. more

Research Summary

Dr. Kraitchman's research interests are concentrated on non-invasive imaging and minimally invasive treatment of cardiovascular disease. 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 mesenchymal stem cells to regenerate infarcted myocardium using non-invasive MR fluoroscopic delivery and imaging. MRI and radiolabeling techniques include novel MR and radiotracer stem cell labeling methods 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 and peripheral arterial disease.

Recently, 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 has been developed. These labeling techniques have been developed using FDA-approved contrast agents in large animal preclinical models of cardiovascular disease using clinical MR, radionuclide and CT imaging scanners for rapid translation to the clinical realm. 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.


The Kraitchman lab concentrates on clinical translation of minimally invasive imaging technology that uses new molecular imaging and nanomedicine techniques to enable stem cell tracking and enhanced engraftment. Recent research efforts in the lab have concentrated on developing x-ray visible stem cells for cardiovascular applications. Using multimodality imaging techniques, the research team confirms stem cell viability with PET and bioluminescence. Then, using conventional devices currently in clinical trials, Kraitchman's researchers image and target stem cells to the heart directly using MRI fluoroscopy with a specialized MRI-compatible device or x-ray fluoroscopic imager.
