3D Mammography

HSHS St. Mary's Hospital now provides 3D mammography services. Our 3D mammography equipment is the newest and most advanced imaging technology and increases the detection rate of invasive breast cancer by as much as 40 percent. This new machine is faster and more accurate and also reduces the need for follow-up imaging.

3D Mammograms use a low-dose X-ray to examine breasts. Mammograms can help detect early breast cancer in women experiencing no symptoms, as well as diagnose breast disease in women with lumps, pain or nipple discharge.

At St. Mary’s Hospital, we’re dedicated to providing the best women’s care in central Illinois. Call St. Mary's radiology department to learn more or schedule a scan at  217-464-2984.

All technologists are licensed by IEMA and registered through ARRT. 

As a Patient:

  • You will need to undress from the waist up at your appointment.
  • The technologist will position your breast to get the best test results.
