What is it?

Maryville Imaging offers our patients Duel Energy X-ray Absorptiometry (DEXA) Bone Densitometry testing, which measures the amount of calcium in a person’s bones and determines if osteoporosis is present. The bone density test procedure is ordered for women who have entered menopause and suspect menopause bone loss and men who have low bone density. Bone density tests are especially important for women over 65 who are advised to get an osteoporosis screening every 2-3 years.

CT Scan

What is it?

A CT is a Computerized Tomography Scan combining the use of X-rays with advanced computer technology to ensure the most accurate diagnosis possible. Maryville Imaging utilizes a state of the art, low dose multi-slice CT scanner to create cross-sectional images of the body using a series of X-ray beams. The beams spiral around the body computing multiple “slices” that are constructed into a complete image by a computer. The system offers more detail than traditional X-rays, making it useful when there is a need to evaluate the size, shape and position of soft tissue structures.

Mammography (Digital 3D)

What is 3D Mammography?

3D Mammography, also known as breast tomosynthesis or digital breast tomosynthesis, is a form of imaging that uses low dose x-rays and computer reconstruction to create 3D images of the breasts. This advanced technology is vital to the early detection and diagnosis of breast disease.

How does 3D Mammography compare to standard X-Ray Mammography?

X-rays, or radiographs, are the oldest and most common form of medical imaging. It is a noninvasive medical test, producing results by exposing parts of the body to small doses of ionizing radiation. Previously, x-rays were the best way to conduct mammographies, however it does not detect all forms of breast disease. It takes images from top-to-bottom and side-to-side while compressing the breasts between a paddle and the imaging machine. Such compression may cause an overlapping of breast tissue, ultimately hiding possible abnormalities. 3D mammography allows for a smaller margin of error, by using an x-ray tube to move in an arc over the compressed breasts. Multiple images are synthesized into a set of 3D reconstructed images.

Spread the Word

Breast Cancer Mammograms Save Lives - Mammograms are one of the best tools available for catching breast cancer early — when it’s most treatable. According to the Centers for Disease Control, the breast cancer mammogram test can reduce breast cancer deaths by approximately 20 to 35 percent in women 50 to 69 years of age and approximately 20 percent in women 40 to 49 years old. With numbers like that, why is it that so many women are skipping this potentially lifesaving test?

On the Decline

The National Cancer Institute (NCI) recommends that by the age of 40, women should have their first mammogram. Mammogram screenings should occur every one to two years. For many years, women were heeding this advice. According to the American Cancer Society, the percentage of U.S. women age 40 and older were getting regular mammograms between the years of 1987-2000. Today, unfortunately, studies show that mammography for breast cancer screenings are on the decline. Whether it’s because of increasing out-of-pocket medical expenses or confusion about the effectiveness of mammography, the reason is unknown.

Reversing the Trend

One thing is clear: If we are going to win the battle against breast cancer, this trend needs to change. The fact is, mammography does work. And that’s why women need to be encouraged to follow their doctor’s advice to get regular mammogram screenings. Maryville Imaging offers quick mammography results and a comfortable environment with a courteous staff. Remind the women you know and love about the importance of regular mammograms or diagnostic mammograms—it just might save their life.

What to Expect

Mammogram preparation is easy! Our technicians ask that patients do not wear deodorant prior to the mammography screening. Mammograms typically take less than 30-minutes. If it’s time for your mammogram, ask your doctor for a referral to Maryville Imaging!

Digital X-ray

What is it?

X-ray is the oldest and most frequently used form of digital medical imaging. For nearly a century, diagnostic medical imaging has been created by passing small, highly controlled amounts of radiation through the human body, capturing the resulting shadows and reflections on a photographic, or digital, plate.

What is it?

Fluoroscopy is a form of diagnostic imaging that uses x-rays with the aid of a contrast agent to capture a moving image of an organ while it is functioning. Fluoroscopic technology is often the most effective way to view the esophagus, stomach, and upper or lower gastrointestinal tract. A contrast material called barium is used to coat the inside of the esophagus, stomach, colon, or rectum to produce a sharp, well-defined image of the anatomy of interest.

What is it?

MRI stands for Magnetic Resonance Imaging (MRI), a non-invasive, quick, accurate and painless technique that delivers high-resolution images without the use of radiation. MRI utilizes the power of magnets, radio frequencies and computer photographic techniques to create a clear picture of the body’s internal structures, allowing physicians to accurately detect and define the differences between healthy and damaged tissues.

What is it?

A diagnostic medical ultrasound is a sound wave which creates an image of internal organs, vessels and tissues in the body. The image is produced by an ultrasound machine when a hand-held transducer operated by an ultrasound specialist is kept in constant contact with the body. The transducer emits an inaudible, high-frequency sound wave that passes through the body and then bounces back to the transducer, creating an image on a television viewing monitor.
