Learning objectives:
  • To become familiar with the strengths and limitations of different technologies used in Digital Breast Tomosythesis
  • To review decicated clinical case taken with different technologies: Infiltrating ductal carcinoma grade 3

This is the mammogram on a 57 year old woman with a past history of breast cysts, an benign microcalcification, and on her current mammogram one can see the breasts are heterogeneously dense. There are a number of circumscribed nodular opacities in both breasts, consistent with the known cysts and scattered microcalcifications, which was unchanged when compared to prior mammograms. The tomosynthesis study. Was performed on the narrow angled system within our practice and one can see that there are a number of circumscribed nodular densities or deep to the left nipple and also some modularity in the medial left breast where there is some linear density spreading out from the opacity, and the question was whether this is true speculation or whether this is just adjacent tissue adjacent. To the nodular masses. That is true on the craniocaudal view and on the lateral projection similarly. There is some modularity posteriorly with some linear densities in or adjacent to the nodule. We felt that this needed further evaluation an the options were to do some kind compression films to try to spread that issue out further or use our second tomosynthesis system, which is the wide angled semen system which we have found useful to evaluate. Find speculations and on the wide angled system as one scrolls through on the lateral projection, one can more readily appreciate these speculations arising from the opacity in the posterior. Left breast and that was true on the lateral link projection an on the craniocaudal view on the craniocaudal view we again see the. Circumscribed benign appearing nodular opacities deep to the nipple but in the medial. Left breast, there is a nodular density, but has obvious speculations arising, which is Mammographic Lee highly suspicious and this was more readily appreciated on the wide angled system when compared to the narrow angled tomosynthesis unit and this lesion was biopsied and biopsy confirmed high grade or grade 3 invasive ductal carcinoma.

SIEMENS Why the angle makes Healthineers the difference - Comparison of 150 and 500 The statements by Siemens' customers described herein are based on results that were achieved in the customer's unique tomosgnthesis, case 2 setting. Since there is no "typical" hospital and many variables exist (e.g., hospital size, case mix, level of IT adoption) there can be no guarantee that other customers will achieve the same results.
