Abass Alavi
Abass Alavi (Persian: عباس علوی) is an Iranian-American physician-scientist specializing in the field of molecular imaging, most notably in the imaging modality of positron emission tomography (PET). In August 1976, he was part of the team that performed the first human PET studies of the brain and whole body using the radiotracer [18F]Fluorodeoxyglucose (FDG). Alavi holds the position of Professor of Radiology and Neurology, as well as Director of Research Education in the Department of Radiology at the University of Pennsylvania. Over a career spanning five decades, he has amassed over 2,300 publications and 60,000 citations, earning an h-index of 125 and placing his publication record in the top percentile of scientists.
Abass Alavi was born in Tabriz, the largest city in northwestern Iran. After graduating from high school in Tabriz, Alavi moved to Tehran and received his medical degree from the Tehran University of Medical Sciences in 1964. He began his training in internal medicine at the Albert Einstein Medical Center and the Philadelphia VA Hospital in 1966. Following subspecialization in hematology/oncology at the University of Pennsylvania, Alavi started his education in medical imaging by enrolling in the radiology department at the Harvard-affiliated Beth Israel Deaconess Medical Center. He joined the University of Pennsylvania School of Medicine in 1971 as a research fellow in nuclear medicine, and was soon appointed to the faculty. He currently holds appointments as Professor and Director of Research Education in the Department of Radiology.
Alavi began his work in tomographic imaging under the guidance of Dr. David Kuhl. He and his colleagues at the University of Pennsylvania were pioneers in performing modern tomographic imaging by utilizing single gamma emitting radionuclides (Single Photon Emission Computer Tomography/SPECT). In 1973, he—along with his colleagues Dr. Kuhl and Dr. Martin Reivich—were the first scientists to conceive the idea of labeling deoxyglucose with positron-emitting fluoride (F-18), leading to the development of FDG. In August 1976, Alavi became the first to administer FDG to a human being and acquire tomographic images of the brain and whole body. He was also among the first to utilize Iodine-123 in the diagnosis of thyroid cancer, MIBG in the assessment of pheochromocytoma, radiolabeled WBCs in the evaluation of infection, and 99mTc in the detection of gastrointestinal bleeds, among a host of other discoveries.
Alavi has been associated with the University of Pennsylvania for all of his career, beginning with a fellowship in Nuclear Medicine in 1971–1973. He was promoted to professor of radiology in 1982, and served as chief of the Division of Nuclear Medicine from 1979 to 2006. Since then, he has been the director of research education in the Department of Radiology.
Alavi has performed numerous research studies utilizing FDG since its inception. Furthermore, soon after the introduction of CT in the early '70s and MRI in the early '80s, Alavi has conducted research that combines PET with these imaging modalities. He is an expert in modern imaging techniques and the clinical applications of PET imaging for the detection of cancer and other disorders including dementia, seizures, cardiovascular disease, and infection.
Alavi served as a member and chairman of scientific study sections at the NIH and American Cancer Society. He has trained and mentored countless students in modern imaging techniques, and many of his former students and research fellows now occupy leadership positions in medical imaging across the world.
Positron emission tomography (PET) is a medical imaging technique that produces a three-dimensional image of molecular processes in the body. The system detects pairs of gamma rays emitted as a result of the annihilation of positrons emitted from radionuclides (tracers), which are used to label biologically active molecules.
One of the factors most responsible for the widespread adoption of positron imaging was the development of radiopharmaceuticals. In particular, the development of labeled 2-Fludeoxyglucose (18F) (2FDG) through the collaboration between scientists at the Brookhaven National Laboratory and investigators at the University of Pennsylvania, was a major factor in expanding the scope of PET imaging. The compound was first administered to two normal human volunteers by Alavi in August 1976 at the University of Pennsylvania.
