Distortion in DBT


Assistant Professor of Tehran University of Medical Sciences Tehran, Iran



Architectural distortion defines as the deformation of the normal structure of breast. Architectural distortion is a suspicious abnormality for the diagnosis of breast cancer. architectural distortion is also more difficult to diagnose because it can be subtle and variable in presentation. Digital breast tomosynthesis (DBT) is a three-dimensional (3D) imaging technique aiming at overcoming some limitations of mammography. It has the potential of improving the visibility of breast structures by reducing overlap of tissues. Therefore, the detectability of lesions is potentially increased while false positives (FPs) due to tissues superimposition can be more easily discarded. Digital breast tomosynthesis (DBT) has been shown to decrease the patient recall rate and improve the sensitivity and accuracy of mammography.DBTmayhavethe mostpotential impact in cases of subtle mammographic findings such as architectural distortion
