Avera De Smet Memorial Hospital's professionally trained team offers a variety of imaging tools for diagnosis and treatment of injuries or diseases. Your physician must order the test, with the exception of a mammography. Mammographys can be self-referred, but a physician's name and address must be provided to send your results.

Mobile CT Scan

Computerized tomography, also known as a CT scan, is one of the most widely used diagnostic tools. Cross-sectional views of the body are processed by a computer and converted into visible images on film. These images, when studied in sequence, can give your physician a 3-D view of your body, and as a result, your medical problems can be diagnosed more accurately.


An ultrasound examination, or sonogram, is a diagnostic test that uses high-frequency sound waves to produce high-quality images of soft tissues and motion within the body. Ultrasound involves no X-rays and can provide medical information that, in the past, may have required surgery.

Ultrasound can detect aneurysms, blood clots, damaged heart tissue, abnormal growths, diseased tissue and, during pregnancy, a baby's size, weight, position and physical condition. Ultrasound is also used to diagnose muscle injuries and some joint problems.


Mammography uses safe, low doses of X-rays to image the inside of breasts and is a more accurate tool for identifying abnormalities in the breast that are far too small to be felt during self-exams. Currently, it is the best way to detect cancer when no symptoms exist. Early detection of small cancers and prompt treatment result in the highest possible cure rates.

Women 40 and Older

According to the American Cancer Society, women age 40 and older should have a screening mammogram every year, and should continue to do so for as long as they are in good health. Mammograms for older women should be based on the individual, her health and other serious illnesses.

If there is a history of breast cancer in your family, your physician may suggest having a mammogram sooner than the recommended age or more often than the recommended guideline.


X-ray examinations provide valuable information about your health and are key in helping your physician make an accurate diagnosis. X-rays are also beneficial in the assistance of placing tubes and other devices in the body.

X-rays use a low, safe dose of radiation to penetrate the body to produce either photographic film or video pictures of internal structures. Common uses of X-rays are:

  • Examining the chest - diagnoses diseases of the heart and lungs.
  • Studying bones - detects fractures.
  • Searching for foreign bodies - pinpoints the exact location of foreign bodies, such as metal.
