Bookshelf Bookshelf Early AI came with a subhuman performance and varying degrees of success. If no one area of an asymmetry is more suspicious for malignancy than any other, biopsy should involve a representative sampling of the entire lesion, if not . Tomosynthesis makes missing such a finding less likely than on conventional mammography alone. In this case, if only 2D digital screening mammography had been performed, the patient would have been scheduled for diagnostic mammography and additional views, ultrasound, and possibly a biopsy. government site. The majority of the time there is no lesion and routine follow-up may be performed. Drawbacks to DBT are the increased radiation for combination exams (FFDM and DBT) and the increased time for reading a study (reported as twice the time). Get an accredited certificate of achievement by completing one of our online course completion assessments. The reason we most often ask someone to return for additional views is because of a summation shadow. This occurs when several insignificant areas of dense tissue appear together in one location on a mammogram, creating a shadow that appears to be a major/significant density.
