Ultrasound imaging of the breast uses sound waves to produce pictures of the internal structures of the breast. It is primarily used to help diagnose breast lumps or other abnormalities your doctor may have found during a physical exam, mammogram or breast MRI. Ultrasound is safe, noninvasive and does not use radiation.
This chapter will review the utilization of breast ultrasound for screening and diagnostic purposes. Currently, ultrasound is primarily used to investigate palpable lesions in women less than 30 years old, to provide further characterization of abnormal mammographic findings, and to guide invasive breast interventions. Innovations in ultrasound technology have improved the detection and diagnosis of breast cancer.
The doctor performed a biopsy and diagnosed Patsy with Stage 2 breast cancer. Watch Patsy's story and learn how she was not alone in her diagnosis. When a suspicious site is detected in your breast through a breast self-exam or on a screening mammogramyour doctor may request an ultrasound of the breast tissue.
A mammogram image has a black background and shows the breast in variations of gray and white. Generally speaking, the denser the tissue, the whiter it appears. This may include normal tissue and glands, as well as areas of benign breast changes e.
Breast ultrasound is an important modality in breast imaging. It is the usual initial breast imaging modality in those under 30 years of age in many countries ref. In assessing for malignancy, it is important to remember that one must use the most suspicious feature of three modalities pathology, ultrasound and mammography to guide management.
A variation, particularly in larger or mobile breasts, is to apply the grid pattern quadrant by quadrant. The implant should be anechoic with well defined margins. Folds are commonly seen in the implant surface.
A lump in the breast is a cause of great concern. High frequency, high-resolution USG helps in its evaluation. This is exemplified in women with dense breast tissue where USG is useful in detecting small breast cancers that are not seen on mammography. Several studies in the past have addressed the issue of differentiating benign from malignant lesions in the breast.
