Positive predictive value of mammographic features on digital breast tomosynthesis

Digital Breast Tomosynthesis

Digital Breast Tomosynthesis (DBT)

DBT is a three-dimensional (3D) breast imaging technology that uses a rotating X-ray source to acquire multiple image slices at several angles. The X-ray source rotates around the breast in an arc. Serial exposures are taken every few degrees in the arc rotation. These images are then reconstituted by software to produce a 3Dimage of the breast, similar to CAT scanning. It has been suggested th...

Texture in Digital Breast Tomosynthesis: A Comparison between Mammographic and Tomographic Characterization of Parenchymal Properties

Studies have demonstrated a relationship between mammographic texture and breast cancer risk. To date, texture analysis has been limited by tissue superimposition in mammography. Digital Breast Tomosynthesis (DBT) is a novel x-ray imaging modality in which 3D images of the breast are reconstructed from a limited number of source projections. Tomosynthesis alleviates the effect of tissue superim...

Digital Breast Tomosynthesis - 06/13

Digital breast tomosynthesis (DBT) is being developed as an approach to generate images that may improve the sensitivity and specificity of mammography. Current radiographic approaches to mammography produce two-dimensional (2D) images. These 2D systems can have limitations due to overlapping tissue in the breast that may hide lesions (cancers) or cause benign masses to appear suspicious. DBT, ...

American Society of Breast Disease Statement on Digital Breast Tomosynthesis

Introduction The widespread implementation of screening mammography has decreased the mortality of breast cancer by as much as 50% [1]. Despite recent controversies regarding the benefits of screening mammography, and the age at which screening mammography should begin, mammography remains the most widely utilized tool for early detection of breast cancer. However, it is also evident that mammo...
