Nuclear Cardiologist

Dr. Keith Medeiros is a Nuclear Cardiologist in Marlborough, MA with special training and skill in using small amounts of radioactive material to diagnose and treat patients' heart problems by injecting an imaging agent into a patient's bloodstream and using a gamma camera to monitor a patient's heart at work and at rest. As a Nuclear Cardiologist, Keith Medeiros, MD performs cutting edge heart scans and tests to provide diagnostics and condition management plans. Nuclear Cardiology is the study and use of noninvasive techniques to assess and evaluate dysfunctions of the heart: blood flow, pumping function, size, and location. Nuclear medicine injects small amounts of radioactive materials - radiotracers - into the bloodstream, nose (inhaled) or mouth (swallowed). These radiotracers travel to the area being examined and give off gamma rays which are detected by a special camera and depicted by a computer as highly detailed images of the heart. Significant diseases and conditions treated by Nuclear Cardiologists include schaemic heart disease, coronary artery disease and cardiomyopathy. Medical tests, procedures and therapies provided by Nuclear Cardiologists include supervising cardiac stress tests and cardiac specific radiotracking, SPECT gamma imaging analysis, fusion/hybrid imaging (structural with CT/MR + functional SPECT/PET), multiple gated acquisition (MUGA), radionuclide angiography, ventriculography, or gated pool imaging.
