Mammography

The Mankato Clinic has two ways of performing mammograms.  Our primary method for screening is 3D (3-dimensional) or tomosynthesis (TOMO).

2D Screening Mammogram

  • X-ray picture of the breast
  • Covered by insurance
  • Might require a callback for additional imaging if findings aren’t clear

3D Tomosynthesis Screening Mammogram

  • Images of breasts in layers and a 2D image
  • FDA-approved superior for women with dense breasts
  • Proven to detect more breast cancers than 2D in women of all breast densities
  • Reduce callbacks for additional imaging by 40%
  • Covered by most insurance

Mammogram Patient Education

There are two types of mammograms, screening and diagnostic. All mammograms are scheduled.
Screening mammograms can be done in either 2D or 3D. Read about the differences below: 

What is a Screening Mammogram?
  • Performed for routine screening where there are NO signs, symptoms, or clinical findings of breast cancer.
  • It is coded and billed as “preventative” and coverage is determined according to your individual insurance benefit package.
  • Approximately 10 percent of patients will have findings on their screening mammogram that require additional imaging for further evaluation.  This additional imaging will occur at a future scheduled appointment.  Please do not be alarmed, the majority of patients returning for additional imaging receive a negative result (not cancer).
  • We will send you a letter with the results. If you do not have a follow-up appointment, your provider will contact you by letter.  Your results will be available on the Patient Portal.
  • A patient with implants has extra views. This is billed as a diagnostic, but coded as a screening/preventative unless there are concerns.

What is a Diagnostic Mammogram?
  • Performed when there are signs, symptoms, or clinical findings such as a lump, nipple retraction, discharge, skin dimpling, swelling, redness, or pain/tenderness or to evaluate a finding on the screening mammogram. Because the diagnostic mammogram is reviewed by the Radiologist during the appointment and an ultrasound is generally performed, an appointment is required.  Results are shared with you at this test and any next steps will be discussed.
  • Diagnostic mammograms are coded and billed as diagnostic, NOT “preventative” or “screening”.  Coverage for this imaging is determined according to your individual insurance benefit package.  Please contact your insurance company directly with questions.
