1 BREAKING THE SOUND WAVES! SURVEY (HAND-HELD) VERSES AUTOMATIC BREAST ULTRASOUND WHAT S THE DIFFERENCE Patricia Gaspard (RT)(M)(R)(CRA)/Marie Barnett (RT)(M)(R) March 16, 2019

2 Hand Held vs ABUS (Automatic Breast Ultrasound ) Objectives After completing this course, the participant should be able: to describe when and why screening breast ultrasound should be used to describe the scanning technique of screening breast ultrasound to describe the differences between Automated Breast ultrasound and Hand held ultrasound to discuss the ultrasound findings of cystic and solid breast masses technologist role in assisting with ultrasound

3 Breast Ultrasound Who, What, When, Where and Why Another imaging tool to define breast masses (solid versus fluid filled) A tool specific for patients with dense breast/additional diagnostic tool No radiation associated/uses sound waves Fast imaging/fast processing Has a Recording option

4 Ultrasound Waves in Bellagio Water Show Utube video

5 Breast Density Many states have laws that require additional imaging for patients with dense breast Mammography is very sensitive to breast tissue that is mostly fatty replaced which is why most screening starts at age 40 Dense breast can hide masses 4 Categories of Breast Density Age is a factor

6 Breast Density Categories Many systems use A, B, C, D to describe the density ratings, with A being fatty and D being extremely dense A B Fatty scattered areas of dense glandular heterogenously dense Dense

7 Types of Breast Ultrasounds Screening Diagnostic Survey Hand held Survey Automated Unilateral/Axilla Mass Specific Research Focused Ultrasound

8 Key Points on Ultrasound Point No Radiation Requires Transducer Contact Solution Produces shades of grey Performer Note Uses Sound Waves Wand instrument that includes crystals in tip for breast scanning Gel for Hand Held/Lotion for Automated Masses are normally dark Tech or Rad for Hand Held Mammo tech/sonographer Automated

11 HOW IS ULTRASOUND PEFORMED Breast ultrasound uses sound waves to make a computer picture of the inside of the breast. A gel is put on the skin of the breast, and a mechanical wand called a transducer is moved over the skin. The transducer sends out sound waves and picks up the echoes as they bounce off body tissues. The echoes are made into a picture on a computer screen. Automated ultrasound is an option that uses a much larger transducer to take hundreds of images that cover nearly the entire breast.

12 Hand Held vs Automated Ultrasound Hand held Advantages Real time Images Seems more personalized Immediate answers Known method Has video option Disadvantages Takes time Not great for Screening Requires highly trained operator Low reproductivity Automated Advantages Covers large area transducer 3D/Projections/Volumes Less False Negatives Perfect for Screening Images can be easily manipulated by radiologist post survey Fast Not operator dependent Disadvantages Can be painful Requires formalized training for radiologist Physicians don t trust it yet
