Scanning Tips
• Minimum bed height should be 30” to achieve proper compression. The compression range indicator
arrows on the articulating arm notify the user when the arm is at its lowest point and compression
cannot be applied.
• Always check to make sure a membrane has been replaced on the scanner assembly.
• Select proper depth to avoid tissue exclusion. Depth can be evaluated by visualizing the chest wall at
the time of initial transducer placement. If the chest wall is not visualized a deeper depth should be
selected.
• Keep the nipple inside the active scan area whenever possible.
• The active scan area should have as much skin contact as possible.
• Breast tissue should be kept level without tilting or mounding.
• Avoid wedging the breast tissue, which causes the ultrasound beam to penetrate the tissue at an
angle which may result in shadowing, artifact and false positives.
• Begin by establishing optimal manual contact and compression of the breast, then activate compression
assist while gradually releasing manual compression.
• Compression level 2 is recommended for most breast tissue. Once the scan has begun, If the transducer
slides or lifts, abort the scan and decrease to a lower level of compression.
• Manual compression is recommended for women who are not able to tolerate any levels of compression,
such as women with fibrocystic breast tissue, islands of dense breast tissue or women with moderate
to large size cysts/masses.
• If the breasts are large and tissue extends more than 15 cm from the nipple, it will be necessary to
obtain views that do not include the nipple in order to ensure coverage of all the tissue. Additional
views include: SUP, INF and UOQ or a second LAT.
• When the breasts are large, the operator obtains a view that includes as much tissue as possible with
the nipple visible and then obtains a second volume of the same view farther in the direction that the
breast tissue extends away from the nipple.
• The transducer should not slide, roll or lift during scanning.
• Remind the patient they can breathe normally but should refrain from talking or moving during the
scan to avoid motion artifacts.
