3D Breast Tomosynthesis
3D Breast Tomosynthesis
at Zilkha Radiology
Breast cancer is the most common form of cancer and the second leading cause of cancer-related death in the U.S in women. Mammography screening has dramatically reduced breast cancer death particularly after the introduction of digital mammography (2D) at the beginning of the 21st century.The U.S. Preventative Services Task Force agrees that annual screening beginning at the age of 40 years saves the most lives.
Digital Breast Tomosynthesis is a 3D imaging modality used in conjunction with 2D digital mammography for breast cancer screening.It is acquired by low dose exposure of a rotating x-ray tube.The obtained 3D images are reconstructed at 1.0 mm thick slices.
3D Breast Tomosynthesis is particularly useful in patients with dense breasts, allowing overlapping structures of the dense breast to be separated.Only structures within the plane of interest remain in focus.The technology improves the ability to detect more cases of breast cancer at a smaller size and at earlier stage.Lives can be saved when breast cancer is found and treated at a smaller size and earlier stage.
Zilkha Radiology has the most technically advanced, up-to-date 3D Mammography. 3D Mammography detects cancer that may be overlooked at 2D Mammography.The rate of diagnosis of cancer increases 27% when 3D is added to 2D mammography.There is a 40% increase in detection of invasive breast cancer when 3D is added to 2D.3D reduces the need for recalls for additional images. 3D mammography reduces false positives, leading to less biopsies.There is less breast compression with 3D particularly important in patients with tender breasts.
Zilkha Radiology also offers stereotactic breast biopsy, ultrasound guided breast biopsy and MR guided breast biopsy.
What is computer-aided detection (CAD)?
CAD uses a digitized mammographic image of the breast to search and detect abnormal areas of density, mass or microcalcification that may indicate the presence of cancer. The CAD system highlights these areas on the images, alerting the radiologist for further analysis.
What can I expect during the procedure?
As with traditional mammography, a radiology technologist will position
you to image your breast. The breast is placed on a platform and mildly
compressed with a paddle.
How should you prepare for the mammogram?
How long does the procedure take?
The mammography procedure takes about 20 minutes.
When will you know the results?
A qualified radiologist experienced in mammography, will analyze the X-rays. The radiologist will send your doctor a written report. You should contact your physician within 2-3 days of your exam to make an appointment to go over your results.
