What imaging technique is typically not utilized to confirm lesion removal post-surgery?

The imaging technique that is typically not utilized to confirm lesion removal post-surgery is a computed tomography (CT) scan. CT scans are primarily employed for visualizing internal structures and assessing conditions in various parts of the body, but they are not the standard method for routine follow-up after breast surgery.

In contrast, ultrasound, mammography, and X-rays are more relevant for post-surgical evaluation in breast cancer care. Ultrasonography can help assess any residual masses and monitor the surgical site for complications such as hematomas or abscesses. Mammography remains essential for evaluating the breast tissue after surgery to ensure that no additional lesions remain and to monitor for any changes in the breast structure over time. X-rays, while not as commonly used specifically for breast assessments, can still provide supplementary information in certain clinical situations.

Thus, the CT scan is less favored for confirming lesion removal because it does not offer the specialized detail necessary for direct postoperative evaluation of breast tissue compared to the other imaging modalities.
