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.

Patient Ratings & Comments
The Patient Rating score is an average of all responses to physician related questions on the national CG-CAHPS Medical Practice patient experience survey through Press Ganey. Responses are measured on a scale of 1 to 5, with 5 being the best score. Comments are also gathered from our CG-CAHPS Medical Practice Survey through Press Ganey and displayed in their entirety. Patients are de-identified for confidentiality and patient privacy.
