Stereotactic biopsy

Stereotactic biopsy, also known as stereotactic core biopsy, is a

X-ray-guided stereotactic biopsy is used for impalpable lesions that are not visible on ultrasound.[1]

A stereotactic biopsy may be used, with x-ray guidance, for performing a fine needle aspiration for cytology and needle core biopsy to evaluate a breast lesion. However, that type of biopsy is also sometimes performed without any imaging guidance,^[2] and typically, stereotactic guidance is used for core biopsies or vacuum-assisted mammotomy.^[3]

Stereotactic core biopsy is necessary for evaluating atypical appearing calcifications found on mammogram of the breast. If the calcifications exhibit the classic "teacup" appearance of benign fibrocystic changes, then a biopsy is usually not necessary.^[4]
