Breast Imaging Ultrasound

An ultrasound of your breasts does not replace a mammogram. If you have recently had a mammogram and have been asked to return for an ultrasound, do not be alarmed. And ultrasound simply gives doctors additional information about areas seen on a mammogram.

An ultrasound allows doctors to view the breast architecture dynamically. Sometimes, ultrasound helps physicians distinguish between cysts and solid lesions.

About half of well-circumscribed masses turn out to be benign, fluid filled cysts. These cysts are recognizable on ultrasound by their oval shape, smooth walls, lack of echos, and echogenically bright areas immediately behind the cyst.

A solid lesion has internal echos. A solid lesion may be benign or malignant. The only way to be sure is to have a biopsy of the area or a follow-up mamogram to check for changes.

When a lump is felt, ultrasound provides a wonderful way to look at a palpable area in a target fashon. You may be asked to locate the area with the lump; a probe with gel will then be placed over the area. You should then allow for 45 minutes for the exam.
