筛查性乳房x光检查

A mammogram is a very safe X-ray exam that uses low doses of radiation to detect changes in the 乳房 that may be too small or subtle to be felt during 乳房 self-exams.

乳房x光检查有助于及早发现早期癌症

Screening mammography is used to find early-stage cancer before it grows large enough that you can feel it and before it has a chance to cause symptoms or spread outside of the 乳房.

Early-stage 乳房 cancer is usually curable and is more easily treated with less invasive and less toxic therapy than is late-stage cancer. Approximately less than 10% of routine mammograms are interpreted as possibly abnormal and require additional 乳房 imaging with mammography and/or 乳房 ultrasound.

Your primary care provider may help decide if supplemental imaging is recommended for you based on your personal and 家族病史. 然而, you are welcome to ask the mammography technologist and radiologist if you have questions about the most appropriate exam for you. 你多久做一次乳房x光检查取决于你的年龄, 家族病史, 患乳腺癌的风险, 整体健康. Screening mammography does not require a physician referral and is covered by most insurance companies.

Mammography exams are performed at by our technologists, who are certified through the 美国放射技师注册(ARRT).

乳房x光检查的类型

We offer the latest 乳房 health services and mammography 乳房 exams including 2-dimensional (2-D) digital mammography and 3-dimensional (3-D) digital mammography tomosynthesis.

二维数字乳房x线摄影

在二维数字乳房x线摄影中, a low dose X-ray beam shines through the 乳房 and creates a digital image receptor, 类似于数码相机的工作原理. This image is viewed on a computer monitor by a mammography technologist in a matter of seconds. The images are then sent electronically for the radiologist to interpret. 考试时间为15到20分钟. 二维数字乳房x线摄影 is the standard 乳房 exam for most women.

三维数字乳房x线摄影断层合成

3-D digital mammography (also known as 乳房 tomosynthesis), is a 乳房 imaging exam that improves the accuracy of mammography. 接受筛查的女性, 3-D digital mammography may be done along with a traditional 二维数字乳房x线摄影 exam. Sometimes, 3-D mammography may be used to evaluate an abnormality like a 乳房 lump.

3-D乳房x光检查和2-D乳房x光检查非常相似. 3d乳房x光检查, 然而, the X-ray tube moves and a series of mini X-ray exposures are obtained, 创建数字数据集, which is then reconstructed into 1-millimeter thick slices (or layers). The radiologist views each individual layer of the 乳房 rather than a shadow of the entire 乳房. 结果是, radiologists can detect 乳房 cancer that was hidden by overlying tissue and that may mimic cancer and lead to a false alarm or unnecessary callback.

3d乳房x光检查的好处包括:

• 早期检测 of 乳房 cancers that may otherwise be hidden by overlying tissue.
• 更大的准确性 识别异常的形状和位置.
• 更少的回调 and helps distinguish harmless abnormalities from real cancers.

You will be asked to undress from the waist up and put on an examination gown. You will then stand in front of the mammography unit, which a special type of X-ray machine. The mammographer will place a 乳房 between two plastic plates and gradually compress for a few seconds. (Compression causes a slight flattening which helps creates a clear picture while reducing X-ray dose.)

The mammographer takes two images of the 乳房, one from the top and one from the side. 然后对另一侧乳房重复检查.
