The purpose of this study was to determine retrospectively the frequency and causes of false-negative diagnoses of lesions evaluated with percutaneous stereotactic biopsy performed with vacuum-assisted probes with the patient prone on a biopsy table.
False-negative findings at stereotactic biopsy were least common with 11-gauge probes and were similar in frequency for calcifications and masses

NB: Comparisons only made between 14G and 11G needles
