Tomosynthesis Can Beat Digital Mammography With 1 Hand Tied Behind Its Back

Background: Mammography has been shown to have a wide-ranging false-negative rate based on multiple studies performed over that past 20 years. Rates are as low as 8% and as high as 66% with many limitations being attributed to overlying fibroglandular tissue that may obscure a neoplasm. Tomosynthesis is a technique that obtains 3D information of the breast and displays the 3D images in thin slices at different depths. The aim is to eliminate the obscuring overlying fibroglandular tissue. Objective: To compare the efficacy of 1-view digital tomosynthesis to 2-view digital mammography when assessing lesions originally detected on 2-view digital mammography. Methods: Patients presenting to a breast imaging center with clinical signs and symptoms or who were recalled from screening for diagnostic workup were identified. All patients underwent routine 2-view digital mammography first. If an abnormality was identified, 1-view digital breast tomosynthesis of the side deemed to be abnormal w more...
