Breast Biopsy

The Hologic Selenia is used in a stereotactic breast biopsy

A breast biopsy is performed to remove cells from a suspicious area in the breast and examine them to determine a diagnosis.

Stereotactic breast biopsy is an x-ray procedure that uses multiple coordinates to precisely determine the location of a tumor or nodule so that a tissue sample may be obtained.

In MRI-guided breast biopsy, magnetic resonance imaging is used to help guide the radiologist’s instruments to the site of the abnormal growth.

An ultrasound-guided breast biopsy uses sonic pulses to create images, rather than relying on low-dose radiation (as in a stereotactic biopsy) to do the same.

Image-guided needle biopsy is not designed to remove the entire lesion, but most of a very small lesion may be removed in the process of biopsy. Image-guided biopsy is performed when the abnormal area in the breast is too small to be felt, making it difficult to locate the lesion by hand (called palpation). With the help of some kind of imaging, your doctor will be better able to locate the lesion, thus ensuring the accuracy of the test.

Digital Mammography

Sand Lake Imaging is now offering the Genius 3D Mammography Exam, a more accurate way to screen for breast cancer.

These digital mammography systems create clearer, more accurate images than an x-ray mammography.

Our top-of-the-line Hologic Selenia Dimensions Tomographic Mammography systems allow for sharp, detailed images with superior resolution, reduced exposure, and less compression time. The fully automatic, self-adjusting, self-releasing tilt compression paddle conforms to the natural contour of the breast, making positioning easier and offering incomparable patient comfort.

Unlike other parts of the body, the breast is composed mainly of soft tissue. When breast tissue is x-rayed, it creates an image that looks something like a smoky haze, making it difficult to see tiny “spots,” called microcalcifications, and other subtle signs of early cancer.

With digital tomosynthesis, the radiologist reviews electronic images of the breast using special high-resolution monitors. The physician can adjust the brightness, change contrast, and zoom in for close-ups of specific areas of interest. Being able to manipulate images is one of the main benefits of digital technology. Another convenience of digital mammography over film-based systems is it can greatly reduce the need for retakes due to over or under-exposure. This potentially saves additional time and reduces exposure to x-rays.

Because they are electronic, digital mammography images can be transmitted quickly across a network. Digital images can also be easily stored and copied without any loss of information, and transmitted in a more streamlined manner, eliminating dependence on only one set of “original” films. It is also more cost effective because there are no films to develop since the images are rendered digitally.

 

 

Breast MRI

Cross-sectional MRI view of the breasts

Breast MRI uses Magnetic Resonance Imaging (MRI) to look specifically at the breast.

It is a non-invasive procedure that doctors can use to determine what the inside of the breast looks like without having to do surgery or flatten the breast (as in a mammogram).

Each exam produces hundreds of images of the breast, cross-sectional in all three directions (side-to-side, top-to-bottom, front-to-back), which are then read by a radiologist. No radiation is involved, and the technique is believed to have no health hazards in general.

The hope is that such non-invasive studies will contribute to our progress in learning how to predict the behavior of tumors and in selecting proper treatments. Breast MRI is an evolving technology and should not replace standard screening and diagnostic procedures (clinical and self exams, mammogram, fine needle aspiration or biopsy). This procedure can be helpful for getting a second opinion, or another look at the breast.
