Overview

Mammography is the "gold standard" for screening and detecting breast cancer. At Oregon Imaging Centers, all of our mammography scanners are the latest state-of-the-art full field digital systems. We are both MQSA certified and ACR accredited. Digital mammography uses low-dose X-rays to capture images of the breast that are read by our sub-specialized radiologists. Benefits include better imaging of dense breast tissue and the chest wall, shorter exam times, and lower radiation dose.

Our commitment to breast health goes beyond screening mammograms. Oregon Imaging Centers has the most comprehensive set of breast health services in Lane County, and is the only facility with radiologists who are sub-specialized in mammography working on-site. In addition to screening mammograms, we offer comprehensive advanced diagnostic breast imaging including breast MRI, ultrasound, biopsy, and diagnostic mammograms.

You can review information specific to your scan by selecting from the 'study type' menu in the left column.

Prep & Safety

  • Please arrive 30 minutes prior to your scheduled; appointment time.
  • Patients are encouraged to leave all jewelry at home. Jewelry, including piercings, must be removed prior to your study.
  • Do not schedule your mammogram the week before your period. The best time is typically one week following your last period.
  • Do not wear deodorant, talcum powder or lotion under your arms on the day of your mammogram, as these substances can cause artifacts on the images.
  • If you have sensitive or tender breasts, consider taking an Advil or Tylenol one hour prior to your mammogram.

For your safety, please notify our scheduling department and technologists if you believe you may be pregnant.

The Experience

Why are you having a diagnostic mammogram and how does it differ from a screening mammogram?

Approximately one in ten women requires a diagnostic mammogram after a screening mammogram. This test is ordered so the radiologist can look more closely at an area of interest. The mammography technologist will capture images of your breast from angles not typically used during a screening mammogram. Generally, women find that there is no additional discomfort caused by diagnostic mammogram compared to a screening mammogram.

Here are a few additional items you will want to know about diagnostic mammograms:

  • They take longer than a screening mammogram. Plan on spending anywhere from two to four hours on the day of your exam.
  • These studies take longer because the radiologist will want to interpret the images before you leave
  • Sometimes the radiologist will wait to see your diagnostic mammogram before ordering an ultrasound. However we are usually able to accommodate both tests on the same day.

During your visit, a patient advocate will show you to the changing area and can assist you if necessary. For a mammogram, we ask that you change into a gown which opens in the front. For your convenience, we recommend that you wear a two-piece outfit on the day of your appointment. Our changing rooms offer secure lockers, but we encourage patients to leave valuables at home. Once changed, our patient advocate will guide you to the mammography sub-waiting area where you will find a selection of magazines and newspapers. If you prefer more privacy, please ask the patient advocate to allow you to wait in your dressing room.

The technologist is specially trained and certified by the American Registry of Radiological Technologists to take care of you during your mammogram scan. During your mammogram, the technologists will position you and place your breast on a platform and compress it with a paddle made of Plexiglas.

Breast compression is necessary in order to:

  • Even out the breast thickness to improve tissue visualization
  • Ensure that small abnormalities will not be obscured
  • Reduce radiation exposure
  • Hold the breast still to eliminate blurring caused by motion study

The technologist will gradually apply pressure until the breast is fully compressed. Inform the technologist if you experience sudden or sharp discomfort.

The technologist will step behind a lead-glass shield while capturing the images. Screening mammograms include a top-to-bottom view and a side view. The process is repeated for the opposite breast.

After The Exam

  • Results will be provided to you on the day of your test by the mammography technologist or the radiologist.
  • A sub-specialized radiologist will interpret your images and prepare a diagnostic report for your physician.
  • Often, no additional test is necessary. If the results from the diagnostic mammogram are inconclusive, typically a biopsy is ordered.
  • Results are usually made available to your physician in two or three days.

What are we looking for?

Diagnostic mammograms are performed to identify the exact size and location of a breast abnormality, to image surrounding tissue and the lymph nodes. This study is typically ordered after a screening mammogram or if a patient had been diagnosed with cancer, and for five years post-treatment. A radiologist may also recommend a diagnostic mammogram when following an area identified on a screening mammogram as suspicious.
