Breast Biopsy

The Hologic Selenia is used in a stereotactic breast biopsy

A breast biopsy is performed when an abnormality is detected and tissue sampling is required for a definitive diagnosis.

Your breast biopsy can be performed using a variety of different imaging techniques. The imaging technique for biopsy is selected by the provider performing the procedure based on your prior imaging results.

Stereotactic breast biopsy This technique uses x-ray images to calculate the location of an abnormality and guides the needle into the area of interest.

MRI guided breast biopsy: This technique uses magnetic resonance imaging to image the location of an abnormality and guides the needle into the area of interest.

Ultrasound-guided breast biopsy This technique uses ultrasound waves to image the tissue and guide the needle into the abnormality. This method does not use any x-ray radiation.

Bone Density Test

A DEXA bone densitometry test is used to aid in the diagnosis of osteoporosis and other conditions that cause bone loss.

It is also a very useful tool for evaluating the effects that treatment has had on those conditions. Just as in a common x-ray, a bone density scan is a painless medical test that physicians use for the diagnosis and treatment of various conditions, such as osteoporosis. The test involves exposing the part of the body being examined to a small amount of ionizing radiation to form pictures of the body. Two beams are fired into the body, one measuring soft tissue and the other measuring bone. The difference between the two readings determines bone density.



An ultrasound display

Ultrasound imaging involves exposing part of the body to high-frequency sound waves to produce pictures of the inside of the body.

Ultrasound exams do not use ionizing radiation (as used in x-rays). Because ultrasound images are captured in real-time, they show the structure and movement of the body’s internal organs as well as blood flowing through blood vessels.

Ultrasound imaging is a noninvasive medical test that helps physicians diagnose and treat medical conditions. Vascular ultrasound provides pictures of the body’s veins and arteries. Prenatal ultrasound provides pictures of a developing fetus. A Doppler ultrasound study may be part of a vascular ultrasound examination. Because of its many uses, an ultrasound is a handy, noninvasive diagnostic tool for doctors to use.

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.

CT Angiography

A CT cross-section of the heart

Coronary artery CT Angiography (CTA) is a special type of x-ray examination used to visualize blood flow in the vessels of the heart.

Patients who have this test will have a small intravenous catheter placed in their arm and will receive an iodine-containing contrast dye to help ensure the best images possible of the coronary arteries. The same I.V. may be used to give a safe medication (commonly used by patients with high blood pressure and heart disease) to slow or stabilize the heart rate for better imaging results.

During the examination, which takes about 10 minutes, X-rays pass through the body and are picked up by special detectors which give the final images. Typically, the higher the number of detectors, the better the image. For this reason, this technique is often called “multi-detector” or “multi-slice” CT scanning.

Sand Lake Imaging has a 64-slice multidetector CT, the highest number of detectors available for clinical imaging.

Coronary Calcium Scoring

Siemens Biograph TruePoint PET/CT machine

A cardiac CT scan for coronary calcium is a non-invasive way of obtaining information about the presence, location and extent of calcified plaque in the coronary arteries.

Plaque is a build-up of fat and other substances, including calcium, which can, over time, narrow the arteries or even close off blood flow to the heart. The result may be painful angina in the chest or a heart attack.

Because calcium is a marker of coronary artery disease, the amount of calcium detected on a cardiac CT scan is a helpful screening tool. The findings on cardiac CT are expressed as a calcium score and can help present an overall picture of your heart health.
