Abstract
With the introduction of small-parts scanners with 7.5and 1 0-MHz transducers, nonpalpable lesions of superficial structures are being detected in increasing numbers [1 ]. These lesions may often require cytologic evaluation by fine-needle aspiration biopsy (FNAB), which is necessarily performed under instrumental guidance. Because currently available high-frequency probes are not ideally suited for the biopsy procedure, we evaluated the use of a linear-array intraoperative biopsy probe for guiding FNAB of superficial lesions.
