Assessment of Digital Breast Tomosynthesis (DBT) in the Screening Environment
The objective of this study is to demonstrate that digital breast tomosynthesis (DBT) in combination with full field digital mammography (FFDM) has the potential to reduce significantly baseline screening recall rates without a loss in the detection of cancers. The primary hypothesis of the study is that DBT in combination with FFDM will reduce baseline screening mammography recall rates in negative examinations by at least 20%.
The FFDM images and the FFDM images with the DBT images will be interpreted independently by two experienced radiologists under standard clinical screening procedures. Recommended recall rates will be assessed and compared as a result of each of the two interpretations.

Medical and Biotech [MESH] Definitions
Radiographic examination of the breast.
The identification of selected parameters in newborn infants by various tests, examinations, or other procedures. Screening may be performed by clinical or laboratory measures. A screening test is designed to sort out healthy neonates (INFANT, NEWBORN) from those not well, but the screening test is not intended as a diagnostic device, rather instead as epidemiologic.
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.
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.
Inflammatory Breast Neoplasms
Metastatic breast cancer characterized by EDEMA and ERYTHEMA of the affected breast due to LYMPHATIC METASTASIS and eventual obstruction of LYMPHATIC VESSELS by the cancer cells.
Tomosynthesis is a new digital mammographic tool which can be performed at the same time as routine screening mammography. It creates CT-like slices through the breast, minimizing the tiss...
Mammography remains the current standard in the detection of breast cancer. However, conventional two-view mammography will not detect all cancers. The major limiting factor of conventio...
The purpose of this study is to compare 3D mammography with digital mammography in women with dense breasts for the detection and evaluation of masses and/or breast cancer.
To compare digital breast tomosynthesis (DBT) with full field digital mammography (FFDM) regarding effectiveness as screening modalities.
The purpose of this study is to determine whether addition of automated whole breast ultrasound to the usual screening mammography in a population of asymptomatic women with mammographical...
In Europe one out of every nine women suffers from breast cancer during her lifetime. Since the introduction of mammography screening programs more breast cancers are being diagnosed when they are sti...
OBJECTIVE: To compare breast density on digital mammography and digital breast tomosynthesis using fully automated software. METHODS: Following institutional approval and written informed consent from...
OBJECTIVES: To compare the diagnostic performance of single-view breast tomosynthesis (BT) with that of dual-view mammography (MX); to assess the benefit of adding the craniocaudal (CC) mammographic v...
OBJECTIVE: To evaluate the clinical value of combining one-view mammography (cranio-caudal, CC) with the complementary view tomosynthesis (mediolateral-oblique, MLO) in comparison to standard two-view...
OBJECTIVE: To determine the performance of combined single-view mediolateral oblique (MLO) digital breast tomosynthesis (DBT) plus single-view cranio-caudal (CC) mammography (MX) compared with that of...
