Preoperative imaging-guided needle placement and localization of clinically occult breast lesions

The clinical value of bilateral breast MR imaging: is it worth performing on patients showing suspicious microcalcifications on mammography?

“…SVAB has advantages in addressing microcalcifications because it has excellent sensitivity and specificity with a very low rate of false-negative results [2,24]. However, approximately 75% of lesions that are detected, suspected, or indeterminate on mammography are benign at biopsy [25], implying that many patients undergo biopsy unnecessarily because the indication for SVAB has not yet been fully established.…”

Preoperative computed tomography-guided percutaneous hookwire localization of metallic marker clips in the breast with a radial approach: initial experience

“…The use of mammography-guided wire localization for metallic marker clips placed percutaneously after SVAB has been previously reported (1). A previous study has described mammography guidance using a parallel-to-chest-wall approach, the standard technique for needle placement in the breast (4). Radiologists always use the parallel-tochest-wall approach by mammography-guided wire localization to avoid complications such as entering the pectoralis muscle or thoracic cavity, producing pneumothorax (1,4).…”

Sonographic evaluation of mammographically detected microcalcifications without a mass prior to stereotactic core needle biopsy

“…For nonpalpable breast lesions, the traditional approach has long been surgical biopsy using mammographically guided needle localization. 13 Recently, SCNB has been proved to be an effective alternative to surgical biopsy and has been widely used for the preoperative diagnosis of nonpalpable breast lesions. SCNB has been particularly useful for lesions associated with microcalcifications because the microcalcifications indicate the tissue layer from which specimens should be taken.…”
