To evaluate changes seen on mammograms obtained after large-core stereotaxic biopsy of the breast.
Twenty-seven patients underwent stereotaxic breast biopsy performed with large-core, 14-gauge needles. At least five core samples were obtained from each lesion. The mammograms obtained before biopsy were compared with those obtained 6 months later in the 24 patients in whom follow-up was performed.
The only changes seen on the postbiopsy mammograms were due to tissue sampling (ie, fewer microcalcifications or defects were seen in areas of lesions from which tissue had been extracted).
Large-core needle biopsy of the breast does not produce change or deformity that can be recognized on mammograms. Parenchymal scarring, architectural distortion, fat necrosis, or other identifiable changes seen after surgical biopsy of the breast are not seen after large-core, stereotaxic breast biopsy.
评估乳腺大芯针立体定位活检后乳房X线照片上出现的变化。
27例患者接受了使用14号大芯针进行的立体定位乳腺活检。每个病灶至少获取5个芯样。将活检前获得的乳房X线照片与24例进行随访的患者6个月后获得的照片进行比较。
活检后乳房X线照片上出现的唯一变化是由于组织取样（即，在已提取组织的病灶区域可见较少的微钙化或缺损）。
乳腺大芯针活检不会产生乳房X线照片上可识别的变化或畸形。乳腺手术活检后出现的实质瘢痕、结构扭曲、脂肪坏死或其他可识别的变化在乳腺大芯针立体定位活检后未出现。
