Molecular Breast Imaging (MBI) is an imaging technique that can identify tumors in mammographically dense breasts often not visible with digital mammography or ultrasound. Mammography uses x-ray technology, so the images of both tumors and dense breast tissue often appear white. Clinical studies show that MBI allows differentiation of the tumor and is able to detect up to 3 times as many cancers in women with dense breast tissue. The radiation dose is roughly equivalent to digital mammography.
Molecular Breast Imaging feels similar to a mammogram, except with much less compression. Before the images are taken, your nuclear medicine technologists injects a radioisotope that is absorbed by cancer cells more than it is absorbed by normal cells, making the cancer cells appear white on the images.
Your physician may recommend Molecular Breast Imaging to help identify questionable findings arising from a mammogram or if lumps are found with a physical exam.
Women who have dense breast tissue may have improved detection of early breast cancer with MBI in conjunction with mammography. Breast density can be determined by your breast radiologist using mammography.
In addition to dense breast tissue, your physician may order MBI if you meet any of the following:
