Molecular Breast Imaging as a Screening Tool for Women With Dense Breasts

Molecular breast imaging is a new nuclear medicine technique for imaging the breast. It uses small field of view semiconductor-based gamma cameras that use Cadmium Zinc Telluride detectors. These have superior spatial and energy resolution to conventional sodium iodide detectors.

Mammography is the process of using low-energy X-rays (usually around 30 kVp) to examine the human breast and is used as a diagnostic and a screening tool.

Technetium (99mTc) sestamibi is a pharmaceutical agent used in nuclear medicine imaging. The drug is a coordination complex consisting of the radioisotope technetium-99m bound to six methoxyisobutylisonitrile (MIBI) ligands.
