Dr. Hovanessian Larsen first began her career working at the University of Miami Medical Center, specializing in breast imaging. She joined the faculty of the USC Keck School of Medicine in 1998, and became the Director of Outpatient Mammography for the LAC+USC Medical Center and the Director of Women’s Imaging for the Department of Radiology (DOR). She has served on administrative and clinical committees for the DOR, and has spearheaded many of the Woman’s Imaging research projects. She incorporated the USC DOR into the American College of Radiology Imaging Network (ACRIN), which is a national multicenter organization supported in part by the National Cancer Institute. In addition to her full-time clinical responsibilities, she participates in local and national breast imaging meetings, lectures to the radiology residents, and is the director of the Women’s Imaging fellowship at USC.
Dr. Hovanessian Larsen is a respected consultant for a number of breast cancer screening initiatives, as well as a recognized leader in mammography interpretation and breast biopsy. She has received significant grant awards from the Susan G. Komen Breast Cancer Foundation and the Whittier foundation. She has been involved in several multi-center trials including the NCI, ACRIN, I-SPY 2, and SWOG. Dr. Hovanessian Larsen is dedicated to improving the diagnosis and treatment of breast cancer through early detection, heightened awareness of risk factors, and developing improved imaging methods. Her area of interest is new breast imaging modalities, including digital breast tomosynthesis, automated whole breast ultrasound, and contrast enhanced breast ultrasound.
