Molecular Breast Imaging: A Novel Technology for Detection of Malignant Breast Lesions
Detection of mreast cancer as early as possible is an ongoing imaging challenge.The purpose of the current study is to assess the clinical performance of the new scintigraphic technology, a dedicated breast gamma camera composed by the new generation of CZT detectots,for assessment of breast pathology specifically in women where current imaging techniques, mainly mammography are suboptimal. These cohort are patients with dense breast tissue and patients who are at high risk for breast cancer by a combination of other metrics, including family history and genetic testing. BRCA, is particularly a relvant health problem among Ashkenazi Jews in Israel.
Recently, a breast-dedicated gamma camera has been used for assessment of breast malignancy in over 1000 women in Mayo Clinic, Rochester, USA. Molecular Breast Imaging (MBI), which utilizes a Cadmium-Zinc-Telluride (CZT) gamma camera for scintimammography, has been shown to have a high sensitivity (91%) for the detection of breast lesions > 5 mm in diameter and 69% for tumors smaller than 5mm.
In Israel , genetic high- risk for breast cancer is highly relevant. We will offer the new imaging technology, to a wide patients population/group from all over Israel , in which the referring physician and/or the breast-imaging physician will look for additional imaging modality. Therefore this stage will include:
- Women with equivocal findings on Mammography, US and/or MRI
- Women with discrepancy between CBE and breast imaging
- Women with dense breast
- Women in high risk for Breast Cancer
Before the imaging procedure each woman will need to fill detailed questionnaire, specific for the study, that will include information on her medical history, family history, gynecology information, menstrual phase, use of hormones etc.
The images will be correlated with other imaging tests including mammography, US and MRI. We will follow up the women for at least 6 months, including biopsy findings and or other clinical and imaging exams.
This phase will include 500 women.

Multiple Pulmonary Nodules
A number of small lung lesions characterized by small round masses of 2- to 3-mm in diameter. They are usually detected by chest CT scans (COMPUTED TOMOGRAPHY, X-RAY). Such nodules can be associated with metastases of malignancies inside or outside the lung, benign granulomas, or other lesions.
A fluid-filled closed cavity or sac that is lined by an EPITHELIUM and found in the BREAST. It may appear as a single large cyst in one breast, multifocal, or bilateral in FIBROCYSTIC BREAST DISEASE.
A infiltrating (invasive) breast cancer, relatively uncommon, accounting for only 5%-10% of breast tumors in most series. It is often an area of ill-defined thickening in the breast, in contrast to the dominant lump characteristic of ductal carcinoma. It is typically composed of small cells in a linear arrangement with a tendency to grow around ducts and lobules. There is likelihood of axillary nodal involvement with metastasis to meningeal and serosal surfaces. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1205)
Neoplasms, Ductal, Lobular, And Medullary
Neoplasms, usually carcinoma, located within the center of an organ or within small lobes, and in the case of the breast, intraductally. The emphasis of the name is on the location of the neoplastic tissue rather than on its histological type. Most cancers of this type are located in the breast.
Fibrocystic Breast Disease
A common and benign breast disease characterized by varying degree of fibrocystic changes in the breast tissue. There are three major patterns of morphological changes, including FIBROSIS, formation of CYSTS, and proliferation of glandular tissue (adenosis). The fibrocystic breast has a dense irregular, lumpy, bumpy consistency.
