The compression paddle is often transparent and comprises a larger biopsy window compared to those typically used with prone or upright S-VAB.
While there are not many disadvantages of DBT-biopsy in the literature, one factor considered a disadvantage by some is that the glandular tissue of the entire breast is exposed during targeting with DBT due to the transparent compression paddle versus exposure to just a small amount of glandular tissue in the often-utilized 5x5 cm window used with PS-VAB.
After the breast is properly positioned by the technologist, the patient can use a handheld wireless remote control to command Senographe Pristina to adjust the compression paddle
based on the patient's comfort level.
Immediately before the compression paddle contacts the lateral breast, the mammographer rotates the patient further medially to help bring lateral tissue forward.
When the final position is achieved, the compression paddle is brought down past the latissimus dorsi, skimming the rib cage.
When placing the breast tissue on the film holder, the mammographer should use the same technique as with female patients, maneuvering from the mobile lateral border and spreading up and out while engaging the compression paddle. When the patient is positioned, the superior edge of the paddle should be directly below the head of the patient's humerus.
The mammographer spreads the patient's breast up and out onto the film holder while engaging the compression paddle. During the procedure, the patient should be instructed to lean forward so that his abdomen does not interfere with the beam.
Partial contact between the skin and the detector or compression paddle
creates a dark artifact that takes the configuration of an area of incomplete contact.
The most important design improvements of the Senographe Pristina, however, are the compression paddles
, which can be controlled by the patient with a remote control, and the friendly looking bucky (that platform supporting the breast), thin and with rounded edges.
Another new design is the compression paddles
, which are described by Hologic as "light and easy to handle." Bulky components are eliminated in the new design, enabling each paddle to mount directly on the compression carriage.
