Mammography Van

Safety measures

For your safety and ours, we are unable to accept walk-ins to provide staff with extra time to thoroughly clean after each appointment. All patients wishing to be screened will need an appointment.

Additionally, you will need to wait in your vehicle until the greeter signals that the van is ready. Each person entering the van will have their temperature taken and be asked screening questions. All patients and staff members must wear masks. Only two patients will be allowed on the van at any one time so that physical distancing is possible.

Mammogram Recommendations Following Vaccine

The Society of Breast Imagining (SBI) has released the following recommended guidelines around the COVID-19 Vaccine and Mammograms.

  • Patients should receive a screening mammogram before the first dose of the COVID-19 Vaccine or
  • Delay screening mammogram exam 4 – 6 weeks following the second dose of the COVID-19 Vaccine

The recommendation helps to prevent false abnormal screening mammograms, which could result in unnecessary diagnostic follow-up.

At the Siteman Cancer Center, we believe mammography screening should be available to every woman, everywhere.

To improve the convenience and availability of mammography, Siteman operates a mobile mammography van that offers screenings by appointment at various locations in the St. Louis area and beyond. Using state-of-the-art digital equipment that emits the lowest possible radiation dose, technologists obtain two-view mammograms. Each exam takes about 20 minutes, requiring very little time from a woman’s busy schedule. Results are reported to the patient and her physician within seven to 10 days.

Our mobile mammography program is the longest running of its kind in the country.  Our newest van, which spans 40 feet in length, is the fourth in three decades for Siteman Cancer Center.

The van is also equipped with high-resolution 3-D digital technology called tomosynthesis. This technology uses X-rays to create multiple images. Then a computer digitally recreates the breast, allowing the radiologist to page through the scans on a computer screen like pages in a book or on an iPad or Kindle, seeing the breast one millimeter at a time. This technology has been shown to not only reduce false alarms, but also help reveal more breast cancers.

The mammography van is certified by the U.S. Food and Drug Administration. The fee will be billed to the patient, her insurance company, Medicare or Medicaid. Women should bring their insurance card to their appointment.

Siteman Mammogram Van


Our radiologists, all of whom are affiliated with the internationally recognized Mallinckrodt Institute of Radiology, sub-specialize in comprehensive breast imaging. That means 100 percent of the time, these specialists are solely dedicated to interpreting breast imaging studies at the main hospital campus and Barnes-Jewish West County Hospital.

All radiology technologists on staff have advanced certification in breast mammography and have undergone rigorous training in breast anatomy and physiology, positioning and compression, as well as imaging of patients with breast implants.

Medical records transfer and second opinions

Previous breast imaging scans done at other institutions can be obtained free of charge for patients interested in transferring medical records to our imaging specialists. Patients must authorize consent for all medical record transfers. Previous images then will be compared to current mammogram studies at our facility. Second opinion consultations also are offered and can be scheduled.

Patient navigation

Specialty trained Breast Health Patient Navigators are available to guide patients through diagnostic and treatment services. Patients or providers may request a patient navigator upon referral or when scheduling an appointment.
