Dr. Avice O'Connell, is a Professor of Imaging Sciences and Director of Women's Imaging at the University of Rochester. She received her medical degree from Trinity College, Dublin, Ireland and her radiology training and subsequent practice in Rochester, NY. She has 30 years of experience in breast imaging and is actively involved in teaching and research evaluating newer imaging modalities.
Dr. O'Connell is a fellow of American College of Radiology (ACR), Society of Breast Imaging (SBI) and the Royal College of Physicians of Ireland.
She specializes in all aspects of breast imaging including screening, diagnosis, minimally invasive biopsies and follow up after cancer diagnosis.
Her research involves new technologies, in particular, cone beam CT of the breast contrast 3D imaging and recently deep learning with Samsung for ultrasound of breast masses.
Dr. O'Connell is a world renowned speaker and is very active in teaching medical students, residents and is frequently solicited for her expert opinion in the media.

I believe I am one of the few radiologists in the world with hands-on experience in dedicated breast CT imaging. Breast CT is now approved for clinical use in Europe, but only a very small part of its potential has been explored. Mammography is the gold standard in routine screening and diagnosis of breast cancer. However, limitations in sensitivity and specificity, particularly in dense breasts, has motivated the development of alternative techniques such as digital breast tomosynthesis, whole breast ultrasound, nuclear medicine imaging methods and more recently dedicated breast CT. I am also very active with research focusing on Cone Beam CT imaging. Cone Beam CT imaging provides pictures of tissue around the ribs and outer breast towards the armpit, where 50 percent of cancers are found. The Cone Beam Breast Computed Tomography scanner takes 360-degree views of breast anatomy and in one case showed a cancer which was hard to detect on a mammogram. So far the Cone Beam scanner has detected every tumor seen on a mammogram. Mammograms in the best hands in the world will miss 15 percent of tumors because they are difficult to read. This is because the mammogram X-ray reduces a three-dimensional structure, the breast, to two dimensions and mammograms often show only part of a tumor, and what appears as a speck on a mammogram is often at the core of a much larger tumor. The process takes only 10 seconds; the breast is allowed to hang through a hole in the table while the scanner takes 300 shots from every angle. The scanner has the same dose of radiation as a mammogram but the procedure will probably cost more; the average cost of a mammogram is $80, while a CT can cost several hundred. Breast cancer remains the biggest cancer killer of women, after lung cancer, with 1.2 million cases globally and 270,000 in the United States alone. It kills 500,000 men and women every year globally and 40,000 in the United States. The University of Rochester has licensed the technology to a Rochester, New York start-up company, Koning Corporation, to make, use and sell Cone Beam scanners.

EA1151 Tomosynthesis Mammographic Imaging Screening Trial (TMIST)
Lead Researcher: Avice M O'Connell
This phase III trial is looking at an advanced 3-D imaging technique, digital tomosynthesis mammography, to screen patients for breast cancer. It uses a low-dose x-ray system and computer reconstructions to create three-dimensional images of the breasts.
This method of screening may be superior to digital mammography for breast cancer screening and may help reduce the need for additional imaging or treatment.
Eligibility: Women of childbearing potential (must not be known to be pregnant or lactating). Must be scheduled for, or have intent to schedule, a screening mammogram.
