This presentation will illustrate how the mammographer can, by using well established techniques, new techniques and optimising the use of new generation equipment, assist in the diagnosis of small breast cancers.
The mediolateral oblique (mlo) is recognised as the view that images the maximum amount of breast tissue. The execution of this view is open to variation in personal preference and expertise. In our unit, clients brought back for assessment following routine screening mammography will sometimes have a repeat oblique film taken. We intend to show how this view is worth considering, early in the diagnostic process, when the abnormality is not seen in the craniocaudal view.
The surgically altered breast can be difficult to diagnose. We will demonstrate a simple technique to identify the surgical scar on the mammogram that then helps to differentiate between scar tissue and a recurring lesion.
We also intend to demonstrate how the use of a high-contrast film and appropriate use of different targets and filters on the newer equipment maximises the amount of diagnostic information on the resulting mammogram.
