MAMMOGRAPHY MISTAKES AND PITFALLS FOR TECHNOLOGISTS


1. Films too light due to technique or poor compression.
2. Doing routine screening without carefully reviewing images before letting patient leave. This is especially true for mammography certified technologists (R.T.(M)) whose special training allows them to aid in the detection of breast cancer.
3. Failure to mark skin mole or other skin lesion leading to callback of the patient for workup of possible breast nodule.
4. Failure to mark the site of scars on the patient history sheet and/or on the skin leading to unnecessary patient recall.
5. Failure to obtain nipple profile view when nipple not profiled on either CC or MLO view.
6. Failure to do at least one magnification view for possible microcalcification cluster.
7. Poor or no visualization of the pectoralis muscle on the MLO view indicating failure to adequately show the upper outer quadrant and axillary region.
8. Exclusion of posterior breast tissue due to poor positioning (inadequate posterior nipple line distance).
9. Failure to do spot compression view for possible architectural distortion in dense tissue.
10. Failure to notice and correct artifacts on screens which can simulate microcalcification clusters.
11. Failure to show a lesion located near the skin (esp. within 1 cm of the skin) with ultrasound. Good imaging of nearfield lesions often needs special focusing, or the use of an offset pad or waterbath attachment.
12. Adding excessive fluid or failing to drain excessive fluid from breast biopsy specimens (esp. core biopsies) prior to specimen radiography.
