Title: Will the role of mammography remain the same in the next five years?
Speaker: Andrew Karellas, PhD, DABR, FAAPM, FACR
The Department of Medical Imaging is pleased to have Andrew Karellas, PhD, DABR, FAAPM, FACR, presenting at our Grand Rounds on Wednesday, June 5th, in the College of Medicine, Room 2117, at 12:00 pm.
Dr. Karellas received his PhD in Medical Physics from UCLA. He came to UA from the University of Massachusetts Medical School, where he was a Professor of Radiology and Director of Radiological Physics. He is certified by the American Board of Radiology (ABR) and he served for several years as Chair of an examination committee at the ABR. He is active as a reviewer for NIH, and he has also served a 4-year term as a member of the National Mammography Quality Assurance Advisory Committee of the FDA.
Dr. Karellas and his team have been funded by various grants from NIH for many years. Ongoing NIH research in his laboratory focuses on research and development of new tomographic imaging systems for breast cancer detection. Other research is aimed at improving image quality and on radiation dose reduction in computed tomography. Dr. Karellas has several issued patents licensed to the industry and products based on his inventions have been marketed worldwide.
Dr. Karellas has been the recipient of many honors including Reviewer “with Distinction” for the journal Radiology, Service Recognition Award as a Deputy Editor for Medical Physics, Lifetime Achievement Award from Upstate New York Association of Physicists in Medicine, Lifetime Service Award from the American Board of Radiology.
Abstract: Mammography has been effective for cancer detection, but it has important limitations particularly in its ability to generate images of dense fibroglandular tissue in the breast. Digital breast tomosynthesis (DBT), also known as “3D mammography” is an extension of digital mammography. DBT devices can generate conventional digital mammograms and mammograms with tomographic detail of breast anatomy. DBT has been in widespread use for over ten years, and it is making an important impact in improving lesion detectability in the breast compared to mammography. Dedicated breast CT is an emerging approach which generates tomographic images in any arbitrary plane of the breast, and it is a fully 3D imaging modality. The utility of these x-ray imaging modalities is discussed against other established imaging technologies like MRI and ultrasound. Consideration will also be given to alternative techniques for imaging the breast, such as ultrasound tomography and photoacoustic imaging.
