Imaging and Radiology at Good Shepherd Marshall

Good Shepherd offers a full range of imaging and radiology services, including X-rays, computerized tomography (CT), ultrasound, mammography, nuclear medicine and magnetic resonance imaging (MRI), to assist physicians in diagnosing illnesses based on each patient’s unique healthcare needs.

Computerized Tomography

Computed Tomography, often times referred to as CT or CAT scan, is an effective diagnostic tool that can see into areas of the body that cannot be seen on a regular X-ray examination. The CT scanner is a doughnut-shaped machine that uses advanced X-ray technology to take pictures of cross-sections of your body, called “slices.” CT makes it possible to diagnose certain diseases earlier and more accurately.

An X-ray is a quick, painless test that produces images of the structures inside your body — particularly your bones.  X-ray beams can pass through your body, but they are absorbed in different amounts depending on the density of the material they pass through. Dense materials, such as bone and metal, show up as white on X-rays. The air in your lungs shows up as black. Fat and muscle appear as varying shades of gray. For some types of X-ray tests, a contrast medium — such as iodine or barium — is introduced into your body to provide greater detail on the X-ray images. 


A mammogram is a high quality X-ray exam of the breast used to detect and diagnose breast cancer and other diseases of the breast. This procedure uses very low doses of radiation. In most cases, a digital mammogram can identify an abnormal breast mass as much as two years before it can be detected by touch. Digital mammography is different from conventional mammography in how the image of the breast is viewed and, more importantly, manipulated. This allows the mammographer to confirm proper positioning and reduces the likelihood of needing repeat exams. In addition, digital technology offers improved visibility of the breast, particularly near the skin line, the chest wall and in women with dense breast tissue.

Screening mammograms are used as a preventive measure for women who have no symptoms of breast disease. A screening mammogram usually involves two views of each breast. Diagnostic mammograms involve additional views of the breast and are used when an abnormality is found during a routine screening mammogram. This method is also used in patients who have complaints including breast mass, pain or skin irritation. Learn more about mammography and women’s health services.

Magnetic Resonance Imaging (MRI)

Magnetic resonance imaging (MRI) is a diagnostic imaging technology that utilizes a strong field magnet and radiofrequency waves to produce pictures or “images” of your internal organs and structures. Because MRI allows your doctor to see inside your body from any angle with great clarity, it gives doctors a wealth of information more quickly than past tests. Learn more about MRI services at Good Shepherd.


Ultrasound imaging, also known as sonography, is a method of obtaining images of the inside of your body through the use of high frequency sound waves. The images are captured in real-time, allowing the physician to see the movement of internal organs and tissues. Learn more about ultrasound services at Good Shepherd.

Bone Density Screening

Bone Density Screening is a simple procedure that determines your bone health. The test measures your bone calcium and density to identify osteoporosis and determine your risk for fractures. Valuable information about the health of your bones can be gathered through this test, often in time to prevent osteoporosis. Call 903.927.6798 for an appointment.
