Montefiore News Releases
NEW YORK CITY, NY (November 6, 2008) -- In the early 1980s when a doctor suspected a patient had heart disease or cancer, the ability to provide an accurate diagnosis through nuclear imaging was limited. It was still a relatively young and undeveloped specialty. Today, high-tech nuclear medicine equipment including next-generation PET/CT scans is allowing physicians to see the tiniest metabolic details to evaluate tumor images, monitor blood flow and evaluate metabolic functions associated with dozens of diseases. A PET/CT scan is an imaging test that combines positron emission tomography (PET) and computed tomography (CT) techniques.
Strides in the field of nuclear medicine, both in the United States and globally, have corresponded to and benefited from the growth of the Department of Nuclear Medicine at Albert Einstein College of Medicine and at Montefiore Medical Center. It is the only department-level program among medical schools and their academic medical center partners in New York City and today is celebrating its 25th year. To commemorate the anniversary, the department is holding a four-day symposium to highlight its achievements.
"Nuclear medicine has played an increasingly important role in collaborating with other specialties, such as radiation oncology, to diagnose and treat cancer and other diseases and engage in studies that lead to a better understanding of these diseases," said Steven M. Safyer, MD, President and CEO, Montefiore Medical Center, where endocrinologist Dr. Sam Seidlin first used radioactive iodine to treat thyroid cancer in the 1940s. "It is the synergy of technology and expertise between departments, and between Montefiore and Einstein, that is producing so many advances in patient care now."
"We have a lot to celebrate," said M. Donald Blaufox, M.D., Ph.D., chairman of the department at Einstein and at Montefiore since its inception in 1982. "Advances in technology over the past two and half decades have vastly improved our ability to diagnose and treat brain and heart diseases, cancer and an array of other serious illnesses," he said. "Recent findings by ourresearchers have produced innovative approaches to treating melanoma and potentially identifying Alzheimer's disease at an earlier stage."
Nuclear Medicine's Role in Identifying Alzheimer's and Treating Melanoma
Einstein has been beta testing time of flight technology to distinguish Alzheimer's disease from healthy brain aging. Working with Bayer HealthCare, Einstein researchers are testing a molecular imaging agent, known as BAY 94-9172, that targets amyloid plaques in the brain. "Amyloid plaques are hallmarks of Alzheimer's which, until now, could only be detected under a microscope after one had passed away. This research could lead to earlier and more accurate diagnosis of the disease," said Joshua R. Steinerman, M.D., assistant professor of neurology and associate director of the Einstein-Montefiore Brain Aging Center.
In collaboration with Arturo Casadevall, M.D., Ph.D., chair and Forchheimer Professor of Microbiology & Immunology, Ekaterina Dadachova, Ph.D., associate professor of nuclear medicine and microbiology & immunology, identified a potential new treatment for melanoma.
"In animal models, Einstein researchers developed a way to deliver lethal radiation to melanoma cancer cells. The antibody molecule armed with radioactive isotope 188-Rhenium binds to free melanin in the cells and destroys cancer cells by bombarding them with radiation emitted by 188-Rhenium," said Dr. Dadachova. This novel approach has cured melanoma in mice and proved safe in human phase 1 clinical trials. Phase 2 clinical trials are in preparation.
From Humble Beginnings to Powerhouse
The department includes a radiochemist and a physicist who are interested in the practice of academic medicine. "This diversity and depth of expertise is unique in the metro region and fosters a high degree of excellence," said Dr. Blaufox. "The 12 faculty members discuss cases on a daily basis, attend tumor boards and conferences in other departments and help to coordinate the results as a team." The department's faculty has also helped to set the standard of medical care in nuclear medicine. For the past 40 years, Dr. Blaufox, along with Dr. Leonard M. Freeman, M.D., vice chair, nuclear medicine at Einstein and at Montefiore, has edited Seminars in Nuclear Medicine, the most respected international review journal in the field.
How Nuclear Medicine Has Changed
Dr. Blaufox continues to marvel at how much technology in nuclear medicine has changed. "In 1982, newly invented renography allowed us to measure the function of each kidney. It was revolutionary. In 2008, we can actually look at the metabolism of the kidney, see how it works and determine what is wrong when it is diseased," he said. What does the future hold? "In the next 25 years, we will see a host of new diagnostic agents emerge for routine use. No organ of the body will be invisible to us. We will be able to observe the function of virtually every organ within the body and detect disease when it is so early that cure will be possible."
