Stereotactic biopsy

Stereotactic core biopsy makes use of the underlying principle of parallax to determine the depth or "Z-dimension" of the target lesion.

X-ray-guided stereotactic biopsy is used for impalpable lesions (cannot be felt manually) that are also not visible on ultrasound.

[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.
