3D Automated Breast Ultrasound System (ABUS)

Zwanger-Pesiri Radiology recently introduced the 3D Automated Breast Ultrasound System (3D ABUS) at its offices in Plainview and Stony Brook.   3D ABUS will complement other breast cancer screening tests - including Digital Mammography, 3D Mammography (Tomosynthesis), and Breast MRI – as part of Zwanger-Pesiri Radiology’s ongoing commitment to detecting breast cancer at the 
earliest possible stage.

3D ABUS is a new approach to performing an ultrasound (or “sonogram”) of the breasts.  During a painless examination that takes approximately 15 minutes, the 3D ABUS device acquires ultrasound images of the breasts, covering each breast in its entirety.  Instead of a small handheld probe, 3D ABUS uses a large curved panel that can typically cover all of the breast tissue in three quick sweeps.

The images are then reviewed by a radiologist on a 3-dimensional work station.  The radiologist is able to look through hundreds of images from multiple angles and see through layers of breast tissue to find cancers, which might otherwise have gone undetected.  The radiologist can compare the 3D ABUS findings to the patient’s mammogram, as well as to prior ultrasound examinations.

Why is 3D ABUS important?  Mammography is a very powerful tool for detecting breast cancer, but it is not perfect.  Approximately 40% of women have dense breasts, and mammography can miss up to 30% of cancers in dense breast tissue.  3D ABUS is not a substitute for mammography, which is still the single best screening test for breast cancer.   However, adding 3D ABUS as a screening test for patients with dense breast tissue can improve cancer detection.

Because 3D ABUS uses sound waves, there is no radiation exposure. Any patient with dense breast tissue, including those with prior breast cancer, breast surgery or implants, can benefit from 3D ABUS. 

Zwanger-Pesiri Radiology is the leading breast imaging facility on Long Island offering 17 locations throughout Nassau and Suffolk counties.

Cryoablation: The Alternative to Surgery for Fibroadenomas

It can all come down to a moment in the shower -- you’re washing up and then, all of a sudden, you feel a lump. Yes, for some, the most regular action on the most average of days has been exactly the moment that sends hearts falling from the normal course of everyday life into an “Oh my, now what will I do?” realization. So it can be with fibroadenomas, the solid, noncancerous breast tumors that occur most often in adolescent girls and women, ages 12 to 35.
Usually painless, fibroadenomas can vary in size and might feel like a marble in your breast, moving under the skin when touched. Among the most common breast lumps in young women, fibroadenomas are a bit of a puzzle in that they can get bigger or even shrink on their own (due to hormonal changes). The first step is discovery, which can take place during a woman’s normal showering routine or through a brief self-examination. A more proactive, clinical way of diagnosing a fibroadenoma is via an imaging test like a mammogram, ultrasound, or MRI. Your doctor will, most likely, recommend one of these imaging tests to confirm that the lump is, indeed, a fibroadenoma.
So how do you deal with a fibroadenoma once discovered? If the fibroadenoma is small and painless, and remains the same size, you would not need any treatment. Often, fibroadenomas can be left alone and no treatment is necessary.  They are, usually, just monitored with follow-up ultrasounds. If however, the fibroadenoma is large, painful, or growing, and your doctor advises treatment, options can include monitoring to detect changes in their size or feel, a biopsy, surgical removal, or cryoablation, an FDA-approved treatment as an alternative to surgery. Cryoablation is a long-established, effective procedure for destroying these types of breast tumors that usually takes between 5 and 15 minutes. After a local anesthetic is applied, a thin hollow needle (called a “cryoprobe”) is used to circulate cooled, thermally conductive fluids which destroy the offensive surrounding tissue (the frozen tissue is absorbed within months). Since no tissue is removed, the shape of your breast will not be affected.

Zwanger-Pesiri Radiology is the only outpatient facility on Long Island performing cryoablation, leading the way in breast imaging.
