Repeats in mammography refer to what?

Repeats in mammography specifically refer to images that must be retaken due to various quality issues, resulting in unnecessary exposure for the patient. This situation usually arises when the initial images are deemed inadequate due to reasons such as poor positioning, motion blur, or inadequate contrast. The main concern with repeats is that they compromise patient safety by exposing them to additional radiation without any diagnostic benefit.

While follow-up exams or additional images might be necessary for further evaluation of findings or to analyze different angles, these do not fall under the definition of repeats. They are part of standard imaging protocols to ensure comprehensive patient assessment, rather than a result of a quality control issue. Therefore, the focus on unnecessary patient exposure distinguishes repeats as a crucial concept in maintaining both the efficacy and safety of mammography practices.
