Zwanger-Pesiri Radiology offers the latest breast ultrasound technology at 17 offices across Nassau and Suffolk counties. Breast ultrasound is frequently used to evaluate breast abnormalities that are found with screening or diagnostic mammography or during a physician performed clinical breast exam.

As part of our commitment to women's healthcare, we are now offering 3D automated breast ultrasound, which has shown to find more cancers in women with dense breasts than with mammography alone.

What is Breast Ultrasound?

Breast ultrasound, also known as sonography or ultrasonography, uses sound waves to make a picture of the tissues inside the breast. A breast ultrasound can show all areas of the breast, including the area closest to the chest wall, which is hard to study with a mammogram. Breast ultrasound does not use X-rays or other potentially harmful types of radiation.

Breast ultrasound does not replace the need for a mammogram, but it is often used to check abnormal results from a mammogram. A breast ultrasound can be used to see whether a breast lump is filled with fluid (a cyst) or if it is a solid lump.

Ultrasound is a great tool for guiding a breast biopsy because it shows structures in real time.

How do I prepare?

Request an appointment online or call us to book your appointment. Once your appointment is booked, your forms will be available on the patient portal.

There are no specific preparations for a breast ultrasound.

Bring with you to your appointment:

  • Prescription from your doctor.
  • Current insurance card.
  • Authorization number from your insurance carrier.
  • Any forms you completed at home.
  • Credit card or cash for your insurance co-pay.
  • Any breast imaging studies that you have from another facility. We like to compare the new mammogram with any previous studies to assist in the diagnostic process.
  • Picture identification.
  • What do I do when I arrive?

    Present your prescription, insurance card and completed forms at the front desk. If any additional forms are required, they will be given to you at this time.

    Be sure to inform the receptionist and technologist if you:

  • Have allergies, specifically to iodine.
  • Are pregnant, think you may be pregnant or are breast feeding.
  • Have breast implants.
  • Have any breast studies from another facility. We like to compare the new mammogram with any previous studies to assist in the diagnostic process.
  • Plan to arrive 15 minutes before your scheduled appointment.

    What happens during the test?

    You can change into a gown if you'd like for the study. You will then be asked to lie down on a comfortable padded examination table. A small amount of gel is placed on the breast. This harmless gel prevents any air from getting between the transducer (ultrasound probe) and your skin to help deliver sound waves into your body most efficiently.

    The ultrasound technologist will then place the transducer gently on your breast where the gel was applied and move the probe around slowly. Changing the direction or the angle of the probe allows the sonographer to get the best possible images of the organ or tissue being examined.

    Once all the images have been recorded, you can wipe off the gel and you are ready to go.

    What happens after the test?

    One of our board certified radiologists specializing in breast imaging interprets your mammogram, compares them to any previous studies and dictates a report. The report is then faxed and mailed to your referring doctor within one or two days. Your doctor will read the report and review the findings with you.

    You will also receive an email or a letter directly from us within one week. If our radiologist feels you need additional views, we will contact you to schedule an appointment and we will also notify your doctor.

    All of your signed reports and images are available to your referring doctor on our physician's web portal, and available to you on the patient web portal.
