When a breast biopsy is recommended for an abnormal mammogram finding, patients may be able to choose a minimally invasive alternative to surgery known as image-guided needle biopsy.当乳房活检，建议不正常的乳房X光检查发现，病人可以选择微创手术替代称为影像引导穿刺活检。 This is a technique that does not require surgery.这是一个技术，不需要手术。 Most of the time, the radiologist performs this type of biopsy.大部分时间，放射执行这种类型的活检。

How Is This Type Of Biopsy Performed?如何这种类型的活检表现？

The needle biopsy can be performed using ultrasound or stereotactic guidance.该穿刺活检可以用超声波或立体定向指导。 Stereotactic refers to the use of stereo images -- pictures of the breast taken from different angles -- to determine the precise location of the abnormal tissue.立体定向是指利用立体图像-图片乳腺采取从不同的角度-以确定确切位置的异常组织。

When stereotactic guidance is used, the patient lies on her abdomen on a specially designed exam table.当立体定向使用的指导，病人是她的腹部的一个专门设计的考试就座。 An opening in the table allows access to the breast.开幕表中可以访问的乳房。 The table is raised and the biopsy is done from below the table.该表是提出和活检是从下面的表格。 This procedure may also be done with the patient sitting upright in a chair - particularly for those who are unable to lie on their abdomen for any reason.这一程序还可以完成与病人身体坐直在椅子-特别是对那些谁不能躺在其腹部以任何理由。 When ultrasound guidance is used, the patient lies on her back on the exam table.超声引导时使用，病人就在于她的考试就座。

The area that needs to be tested is centered in the window of a specially designed compression paddle.该地区的需要为中心测试的窗口中的一个专门设计的压缩桨。 Mammogram films are taken so the radiologist can examine the breast tissue to be biopsied.乳房X线照片影片采取的放射可以检查乳房组织的活检。 These films are called SCOUT films.这些电影被称为童子军电影。

After giving a local anesthetic, the radiologist makes a small opening in the skin.后给予局部麻醉，放射科作出的一个小型开放的皮肤。 A sterile biopsy needle is placed into the abnormal breast tissue.无菌活检针放入异常的乳腺组织。 Computerized pictures help confirm the exact needle placement using digital imaging.计算机的图片帮助确认针的确切位置使用数码相机。

Tissue samples are taken through the needle.组织样品，通过采取针。 It is common to take multiple tissue samples (about three to five).这是共同采取多种组织样品（约三至五年）。 There are a number of biopsy instruments that can be utilized to obtain the tissue sample.有一些切片工具，可以用来获取组织样本。 They include core biopsy which uses a needle to obtain a piece of tissue about 1/16 inch across and ½ inch long, and a vacuum assisted needle biopsy device (VAD), which uses vacuum suction to obtain a tissue sample.它们包括核心使用活检针获得一块组织约1 / 16英寸跨越和半英寸长，以及真空辅助活检装置（ VAD方案），它使用负压吸引获取组织样本。 This tissue is then examined under the microscope to look for cancer cells.这个组织审查，然后在显微镜下寻找癌细胞。 This part of the biopsy takes approximately 15 minutes.这部分的检查大约需要15分钟。 Upon completion, sterile strips and a small adhesive bandage are applied to the skin.工程完成后，育带和一个小胶绷带适用于皮肤。 The entire procedure takes approximately 30 minutes to an hour.整个过程大约需要30分钟至1小时。 Results are usually available in three to five working days.结果通常可在三至五个工作日。

What Are The Benefits Of Minimally Invasive Biopsy?有什么好处微创活检？

Minimal scarring instead of a large incision.最小的疤痕，而不是大切口。
Reduced post-procedural pain and risk of infection.降低后的程序性疼痛和感染的危险。
Potentially lower hospital costs.有可能降低住院费用。
Immediate return to work.立即恢复工作。
Shorter recovery time and immediate resumption of daily activities.恢复时间短，并立即恢复日常活动。
