Dense breast tissue can mask the appearance of tumors and limit the performance of mammography. When used as an adjunct to mammography, Invenia ABUS from GE Healthcare has been shown to improve invasive breast cancer detection by 55% over mammography alone.
These CT images show placement of a 3-D fixed array implanted fiducial (3-D marker) at the time of oncoplastic tumor resection. The original LCTV (LCTVo) was retrospectively re-contoured by the radiation oncologist (LCTVro) and breast surgeon (LCTVbs). Thereafter, both re-contours were combined to create the collaborative LCTV (LCTVc), which required agreement of both the radiation oncologist and breast surgeon. Volume differences between the original LCTV (LCTVo) and the collaborative LCTVc were then evaluated, and demonstrated a mean and median reduction in LCTV.
