Samuel Lewis, MD

Nuclear Cardiologist

Dr. Samuel Lewis is a Nuclear Cardiologist in Frisco, TX 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, Samuel Lewis, 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.

A nuclear medicine physician who specializes in nuclear cardiology.

Nuclear Radiologist

Dr. Samuel Lewis is a Nuclear Radiologist in Frisco, TX with special training and skill in using radioactive materials - radiopharmaceuticals - to produce images of patients' organs that help a nuclear medicine physician diagnose disease. As a Nuclear Radiologist, Samuel Lewis, MD performs imaging of body organs using radiopharmaceuticals. Nuclear Radiology is a method of producing images by detecting radiation from different parts of the body after a radioactive tracer is given to the patient. Significant diseases and conditions treated by Nuclear Radiologists include hyperthyroidism, thyroid cancer, solid tumors, hematologic malignancies, or painful bone metastases. Medical tests, procedures and therapies provided by Nuclear Radiologists include scintigraphy, positron emission tomography (PET) scan, hepatobiliary iminodiacetic acid (HIDA), radioactive iodine thyroid scan.

A radiologist who is involved in the analysis and imaging of radionuclides and radiolabeled substances in vitro and in vivo for diagnosis and the administration of radionuclides and radiolabeled substances for the treatment of disease.
