MRI guided breast biopsy

Posted Jan 30 2012 3:55pm

The American College of Radiology (ACR) has established guidelines to help uniformly assess the criteria for performing stereotactically guided breast biopsy for each modality including MRI. The ACR recommends that lesion visualization and access, availability of the imaging modality, efficiency, safety, and the practitioner's experience are all used to determine the best guidance technique.

The MRI-guided biopsy is more cost-effective compared to a surgical biopsy and costs less.It si less expensive nad has fewer complications.  Less scarring has a cosmetic benefit but also reduces the chance that the scar could obscure underlying tissue on mammography. Recovery time is minimal. The diagnosis is often made faster because of better access to biopsy suites than operating rooms. On the other hand, MRI is not the modality of choice for biopsying lesions that can be easily identified by mammography or sonography.
