Learning objectives:
The aims of our study were: To review the principle and the technique of realization of the Digital Breast Tomosynthesis (DBT) To specify the current indications, inputs and limitations of this technique comparing to conventional mammography.
The quality of the image is a major issue in senology. The advent of digital mammography, thanks to Full Filed Digital Screening Mammography (FFDSM), has greatly improved the detection performance of radiologists. Mammography is the only tool whose use in screening and has shown a decline in mort[...]
Findings and procedure details:
A. PROCEDURE DETAILS 1.Technique (Figure 1): Tomosynthesis uses a set of projections acquired from different angles. Acquisition of images is performed by cranio-caudal displacement of the X-ray tube on a circular arch with a variable angle depending on the machine (15/20/50°) (4). The displac[...]
DBT is an emerging technique, with indications that join the 2D mammography ie individual screening and diagnostic. A beneficial effect of DBT on the detection, location and characterization of breast lesions was been proven in several studies. DBT improve the BI-RADS categories assessment, decrea[...]
