Scintimammography is a type of breast imaging test that is used to detect cancer cells in the breasts of some women who have had abnormal mammograms, or for those who have dense breast tissue, post-operative scar tissue or breast implants, but is not used for screening or in place of a mammogram.
In patients where MRI is contraindicated (certain implantable devices, certain kidney conditions) or in those who prefer to avoid MRI (claustrophobia), molecular breast imaging is a viable alternative. MBI has shown to increase detection of breast cancer in dense breasts by 7-16 cancers per 1000 screens. [1] [3] [5]

[1] [2] The American College of Radiology, Society of Breast Imaging, and American Cancer Society recommend yearly screening mammography starting at age 40. [3] The Canadian Task Force on Preventive Health Care (2012) and the European Cancer Observatory (2011) recommend mammography every 2 to 3 years between ages 50 and 69.
Positron emission mammography (PEM) is a nuclear medicine imaging modality used to detect or characterise breast cancer. [1] Mammography typically refers to x-ray imaging of the breast, while PEM uses an injected positron emitting isotope and a dedicated scanner to locate breast tumors.
In modern (helical) CT, the source/detector makes at least a complete 180-degree rotation about the subject obtaining a complete set of data from which images may be reconstructed. Digital tomosynthesis, on the other hand, only uses a limited rotation angle (e.g., 15-60 degrees) with a lower number of discrete exposures (e.g., 7-51) than CT.
Scintimammography has a high sensitivity and specificity for breast cancer, both more than 85%. [ 7 ] More recently, breast radiologists administer lower doses of 99m Tc sestamibi (approximately 150–300 MBq or 4–8 mCi) for Molecular Breast Imaging (MBI) scans which results in a high sensitivity (91%) and high specificity (93%) for breast ...
Mammography is a common screening method, since it is relatively fast and widely available in developed countries. Mammography is a type of radiography used on the breasts. . It is typically used for two purposes: to aid in the diagnosis of a woman who is experiencing symptoms or has been called back for follow-up views (called diagnostic mammography), and for medical screening of apparently ...
