Positron Emission Mammography and Standard Mammography in Women at High Risk of Breast Cancer

OBJECTIVES: * To install the breast Positron Emission Mammography system and to test and ensure its compliance with all regulatory agencies including the American College of Radiology and the Food and Drug Administration. * To measure and compare the number of call-backs for positron emission mammography (PEM) imaging and conventional mammography. * To measure and compare patient satisfaction for both conventional mammography and positron emission mammography in terms of comfort and pain. OUTLINE: Patients undergo a conventional two-view mammogram and positron emission mammography (PEM). Immediately following treatment, patients complete a questionnaire on their satisfaction with the standard mammogram and the positron emission mammography. After completion of study treatment, patients are followed annually.
