Scintimammography: the new role of technetium-99m Sestamibi imaging for the diagnosis of breast carcinoma.
Technetium-99-Sestamibi scintimammography has emerged as a new procedure for the imaging of breast tumors. Currently, a large clinical experience has been developed and the results published. At the present time, the major drawback of this procedure appears to be its low sensitivity for the detection of breast carcinomas smaller than 1 cm in diameter. There are other biologic and technical issues that remain to be overcome to optimally image the breasts. Some of these include: development of a dedicated breast imager using nuclear medicine techniques, development of stereotactic needle localization of the abnormalities that demonstrate focal increase uptake in women with normal mammogram and breast physical examination, manufacturing of a breast compression device so that we can immobilize the breast in place for more adequate imaging, overcoming the issue of unilateral or bilateral diffuse breast uptake that is noted in 7-10 percent of the cases and finally, determination of optimal dose and imaging factors. This review includes our experience at Harbor-University of California, Los Angeles Medical Center with the use of this agent for breast imaging since 1992.
