Breast Ultrasound Teams

Automated Whole Breast Ultrasound Study (AWBUS)

  • Available in Ames (1215 Duff location).

AWBUS is an additional screening tool for women with dense breast tissue that can aid in the detection of cancers when performed in addition to mammography. (It is not a replacement for mammography.) Women who have dense breast tissue and choose not to undergo a breast MRI screening can choose AWBUS.

The Exam

Which is exam is right for me?

  • Diagnostic Breast MRI
  • Abbreviated Breast-MRI
  • AWBUS

 Use this tool to help you decide.

The exam takes 20 to 30 minutes. You will be asked to lie on your back, slightly rolled to each side for the exam. The scanner is guided by a sonographer to make sure continuous contact is made with the skin. Cine-clip images are then sent to the radiologist to review for any abnormalities. Similar to a mammogram, if an abnormality is identified by the radiologist, a focused breast ultrasound will be performed at a separate time to investigate any abnormalities.

Insurance

Most insurance companies will apply the costs of this imaging study to the medical/deductible portion of your insurance. You may be responsible for up to $400 for this exam. If you would like to discuss the cost with your insurance company prior to this exam, provide them with the CPT code 76641-50 for each breast and diagnosis code R92.2.


Breast Ultrasound

  • Available in Ames (1215 Duff location), Carroll and Marshalltown.

Targeted ultrasound evaluates palpable lumps in the breast and investigates abnormalities identified on Mammogram, AWBUS or breast MRI. Ultrasound can help determine if a lesion is benign or if it requires further evaluation with a biopsy.

The appointment may take up to 45 minutes. The images the sonographer obtains will be shown to a radiologist at the time of the exam.


Ultrasound Guided Breast Biopsy

  • Available in Ames (1215 Duff location).

Ultrasound guided breast biopsies are an outpatient procedure performed by the radiologist. No general anesthetic is required–only local anesthetic within the breast tissue. A small incision is made into the skin, and the biopsy needle is directed to the lesion with ultrasound guidance. Biopsy samples are obtained, and a biopsy clip is placed to identify the site of biopsy. The tissue samples are evaluated by the pathologist, and a report is sent to your doctor.
