To describe the technique of specimen radiography in stereotaxically guided core biopsies and evaluate its role in detection and diagnosis of microcalcifications in breast tissue.
Specimens from 361 stereotaxic breast core biopsies of 72 nonpalpable lesions with mammographic evidence of microcalcifications were obtained from 65 patients. Specimens were placed in saline on microscope slides and radiographed.
Microcalcifications were detected radiographically in 146 of 361 (40%) cores. If calcifications were present on specimen radiographs, histologic detection of these calcifications was made in 114 of 146 (78%) specimens, and diagnosis was made in 118 of 146 (81%). If calcifications were not present on specimen radiographs, histologic detection was obtained in 27 of 215 (13%) specimens and specific diagnosis in 81 of 215 (38%).
Specimen radiography should be routinely performed in stereotaxic core biopsies of breast microcalcifications to ensure appropriate tissue has been obtained and to direct pathologic diagnosis of the tissue specimens.
描述立体定向引导下的粗针活检中样本射线照相技术，并评估其在乳腺组织微钙化检测和诊断中的作用。
从65例患者的72个乳腺X线摄影显示有微钙化的不可触及病变中获取361例立体定向乳腺粗针活检的样本。将样本置于载玻片上的盐水中并进行射线照相。
在361个样本中，通过射线照相检测到146个（40%）样本中有微钙化。如果样本射线照片上存在钙化，则在146个样本中的114个（78%）样本中通过组织学检测到这些钙化，并且在146个样本中的118个（81%）样本中做出了诊断。如果样本射线照片上不存在钙化，则在215个样本中的27个（13%）样本中获得了组织学检测结果，在215个样本中的81个（38%）样本中做出了明确诊断。
在乳腺微钙化的立体定向粗针活检中应常规进行样本射线照相，以确保获取到合适的组织并指导组织样本的病理诊断。
