直接檢體攝影於立體定位真空抽吸輔助乳房切片檢查：個案討論

立體定位真空抽吸輔助乳房切片檢查（stereotactic vacuum-assisted breast biopsy，SVABB）因可提供低侵襲性、快速和耗時短等的優勢，因此廣泛使用於微小鈣化點取樣檢查當中。於真空抽吸輔肋之下，SVABB相較於傳統粗針切片檢查可取得更多含微小鈣化點的乳房切片檢體（breast specimen）。當抽取出乳房切片檢體含有足夠且大量的微鈣化點，可降低癌症診斷的偽陰性率（false negative rate）和取樣誤差。因此，於乳房切片檢查當中取得富含大量微小鈣化點的檢體組織，為提升診斷準確性的重要關鍵。過去需於SVABB檢查後將抽取出檢體移至一般乳房攝影室執行檢體攝影，但此過程會延長SVABB檢查時間而增加病人不適感。本案例為一49歲女性，於乳房攝影檢查發現疑似惡性病灶，經由門診醫師安排進行SVABB檢查。由此案例介紹如何經由直接檢體攝影（direct specimen mammography），來改善SVABB檢查流程並同時維持檢體攝影的影像品質。

The stereotactic vacuum-assisted breast biopsy (SVABB) technique increasingly used to retrieve microcalcification detected by mammogram due to it can provide a minimally invasive, faster and less expensive method. Vacuum breast biopsy can retrieve more sufficient specimen with microcalcification than conventional core biopsy. Retrieved harvesting, larger specimen with microcalcification result in decreased false negative rate and reduced sample error. Therefore, the accuracy of SVABB diagnostic depend on the number, volume suspicious calcification taken. However, conventional specimen radiography need transport retrieved specimen to another examination room to perform specimen radiography. This process can prolong SVABB procedure time and increase patient uncomfortable. In this case, a mammography image of 49-year-old woman was found suspicious malignant lesion. Afterwards, the physician arranged SVABB examination. We introduced using direct specimen radiography that can improve SVABB procedure and maintain image quality in direct specimen radiography imaging.
