Objectives: After studying the article entitled “Carotid Plaque Characterization Using Quantitative Shear Wave Elastography: A Pilot Study,” you will be able to:
Identify Gray-Weale (GW) classification categories
Differentiate between shear wave elastography (SWE) techniques
Describe stiffness levels associated with vulnerable plaques
Predominantly echogenic lesions with small areas of sonolucency describes which GW classification criteria? Type I Type II Type III Type IV
Which method assesses plaque stiffness within one area of a lesion? Push point Point shear wave elastography (pSWE) Young’s modulus 2D shear wave elastography (2dSWE)
How much did the exam time increase when adding SWE to the protocol? 2 minutes 5 minutes 10 minutes 12 minutes
To avoid off-axis imaging, which scan plane was used for pSWE acquisitions? Sagittal Coronal Oblique Transverse
Vulnerable plaque is associated with which Young’s modulus (YM) level? Low Moderate High None
