Breast-Specific Gamma Imaging more effective than ultrasound in finding cancers
September 28, 2015
Another recent study, by Edward Hendrick, PhD., reported in the August 2010 issue of Radiology that the radiation dose from BSGI was higher than mammography and recommended that it should not be used in annual screening without evidence of disease or significant risk of developing breast cancer. "We couldn't agree more and that is not the role for this technology," said Dr. Anne Rosenberg. "We often see patients with mammograms that are very difficult to interpret, but provide some indication that there might be cancer lurking in the dense tissue. Historically, ultrasound would be used to examine these patients and often the results would be equally confusing because both mammography and ultrasound examine the anatomy or structure of breast tissue. For patients with dense breasts, there is a lot of structure to look through which can potentially obscure the features common to breast cancers."
Rosenberg concluded that for patients with dense breasts and an unresolved clinical concern, the benefit of performing BSGI outweighed the radiation risk by a factor of 295:1. "The risk of a missed cancer is huge compared to the small radiation dose the patient receives in a BSGI study. As physicians, we are always weighing the risk of all medical procedures against their benefit to the patient. There is no question that for these patients the benefit of BSGI is well worth the risk."
