Overview

Imaging guided biopsy obtains tissue for diagnosis of breast lesions. Techniques include ultrasound stereotactic and MRI guided approaches. Accurate targeting reduces sampling error and improves diagnosis.

Ultrasound Guidance

Ultrasound guided biopsy is real time and widely available. It is used for lesions visible on ultrasound and allows immediate sampling. Local anesthesia and core needle techniques provide diagnostic tissue.

Stereotactic Guidance

Stereotactic biopsy uses mammographic localization for non palpable lesions. It is effective for microcalcifications and subtle mammographic findings. Compression and targeting ensure accurate sampling.

MRI Guidance

MRI guided biopsy targets lesions seen only on MRI and not on other modalities. It requires specialized equipment and expertise. MRI guidance expands diagnostic options for complex cases.
