Biopsy, breast, with placement of breast localization device(s) (eg, clip, metallic pellet), when performed, and imaging of the biopsy specimen, when performed, percutaneous; first lesion, including magnetic resonance guidance

A percutaneous breast biopsy is a minimally invasive procedure that allows for the collection of tissue samples from breast lesions using magnetic resonance imaging (MRI) guidance. This technique is particularly advantageous as it does not involve radiation exposure, making it a safer option for patients. MRI utilizes the magnetic properties of hydrogen atoms present in the body, which emit radiofrequency signals when subjected to radio waves in a strong magnetic field. These signals are processed by a computer to create high-resolution, three-dimensional images of the breast tissue, enabling precise localization of the lesion. During the procedure, the skin over the target area is cleansed, and local anesthesia is administered to minimize discomfort. The biopsy needle, which may be equipped with specialized features such as metallic ringlets or a signal-receiving coil, is then guided into the lesion under MRI supervision. Depending on the method used, multiple core needle insertions may be necessary to obtain sufficient tissue samples. In cases where an automated vacuum-assisted or rotating biopsy device is employed, a small incision is made, and the device is used to collect multiple samples efficiently. Following the biopsy, a localization device, such as a metallic clip or pellet, may be placed at the biopsy site to mark the location for potential future surgical procedures, such as a lumpectomy. This comprehensive approach ensures accurate diagnosis and facilitates subsequent treatment planning.
