Yiyan Liu, MD

Nuclear Medicine Doctor

A nuclear medicine specialist employs the properties of radioactive atoms and molecules in the diagnosis and treatment of disease and in research. Radiation detection and imaging instrument systems are used to detect disease as it changes the function and metabolism of normal cells, tissues and organs. A wide variety of diseases can be found in this way, usually before the structure of the organ involved by the disease can be seen to be abnormal by any other techniques. Early detection of coronary artery disease (including acute heart attack), early cancer detection and evaluation of the effect of tumor treatment, diagnosis of infection and inflammation anywhere in the body and early detection of blood clot in the lungs are all possible with these techniques. Unique forms of radioactive molecules can attack and kill cancer cells (e.g., lymphoma, thyroid cancer) or can relieve the severe pain of cancer that has spread to bone

Nuclear Cardiologist

Dr. Yiyan Liu is a Nuclear Cardiologist in Louisville, KY 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, Yiyan Liu, 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.
