  • The Radiology Department at Froedtert South uses a variety of imaging equipment to look inside the body and help physicians make accurate diagnoses and determine the best course of treatment.

    Among the imaging services provided by the Radiology Department are:

    Computed Tomography (CT or CAT):  A CT scan creates detailed cross-sectional images of bones, blood vessels, organs and other soft tissue. These images allow doctors to see a single plane view or to create three-dimensional images of areas that need treatment. CT scans are often used for cancer detection because the images help doctors see tumors, their sizes and locations. A CT scan is non-invasive and painless. In emergency cases, a CT scan can show internal injuries and bleeding.

    Ultrasound (sonography): This equipment emits inaudible sound waves and records them when they are reflected back by the body’s internal structures. The reflections are used to generate a computer image. Ultrasound, which has no known harmful effects, is often used to help diagnose pain, swelling and infections. It is also the preferred method for monitoring the health of pregnant women and their unborn children.

    Magnetic Resonance Imaging (MRI): MRI equipment combines a powerful magnetic field, radio waves and a computer to produce detailed pictures of the body's internal structures.  An MRI often reveals things that aren’t picked up by ultrasound, CT scans or X-rays. It is used to evaluate the body for a variety of conditions, including tumors and diseases of the liver, heart, and bowel. Like CT scans and ultrasound, an MRI is non-invasive and uses no ionizing radiation.

    X-ray: X-rays have been used for decades to help physicians look inside the body to diagnose problems. They often are used to diagnose broken bones, look for injury or infection or to locate foreign objects in soft tissue (like an accidentally swallowed coin). X-ray equipment passes a small amount of radiation through the body to create images.

    Mammography: A mammogram is a specific type of breast image that uses low-dose X-rays to detect cancer early, when it is most treatable. Mammography can show changes in the breast up to two years before you or your physician can feel them.

    Nuclear Medicine:This type of imaging uses small amounts of radioactive material, a special camera and a computer to create images of the inside of your body. It provides data that might be difficult to obtain with other types of imaging. Nuclear medicine is used to help diagnose many types of cancers, heart disease, gastrointestinal, endocrine, neurological disorders and other health conditions.

    Positron Emission Tomography/Computed Tomography Imaging (PET/CT) : PET/CT combines the functional information from a Positron Emission Tomography (PET) exam with anatomical information from a Computed Tomography (CT) exam in one single exam.  A PET scan detects changes in cellular function specifically, how your cells are utilizing nutrients like sugar and oxygen.  Since these functional changes take place before physical changes occur, PET can provide information that enables your physician to make an early diagnosis.
