Learning objectives This poster is to review the artifacts that are commonly identified when performing breast elastography both strain elastography and shear wave elastography imaging.  A review of the techniques for both strain elastography and shear wave elastography are presented along with the results of meta-analysis of both strain and shear wave elastography.Teaching Points: 1. Artifacts in breast elastography are common and can lead to false positive and false negative results.2. Recognizing breast elastography artifacts and knowing how to avoid them is...
Read more Background A review of the literature was performed to identify breast elastography artifacts in both strain elastography and shear wave elastography.  Several artifacts are discribed and details why it occurs and if it is possible to adjust technique to eliminate the artifact.  If the artifact has some diagnostic information it is described.  A review of meta-analysis of both strain and shear wave are reviewed and included in the results.  Computer simulation of some artifacts is presnted to help describe why the...

Describe common breast elastography artifacts and how to recognize them and avoid them1. Artifacts associated with cystic lesions.2. The "blue" or "soft" cancers.3. The Bang artifact.4. Artifacts due to poor position of the transducer.5. How to recognize noise.6. The sliding artifact.7. The effect of precompression or preload.8. Use of the quality map in shear wave...
Read more Conclusion Artifacts in breast elastography are very common and occur in both strain elastography and shear wave elastography. Understanding these artifacts is important to limit inaccurate intrepretation leading to false positive or false negative results.  Several of these artifacts have diagnostic information which can be used to improve diagnostic performance.  The artifacts seem can be seen only in strain elastography or only in shear wave elastography.  The ability to perform both strain and shear wave elastography can often allow the recognisition...
