TEACHING POINTS

1. To review the technique of both Strain Elastography (SE) and Acoustic Radiation Force Impulse Imaging (ARFI). 2. To suggest an appropriate thyroid SE and ARFI imaging examination protocol. 3. To demonstrate the elastographic imaging findings in benign and malignant thyroid nodules. 4. To review the potential elastography pitfalls. 5. To suggest an appropriate reviewing method.  

TABLE OF CONTENTS/OUTLINE

Thyroid nodules were examined with SE and ARFI imaging in more than 50 consenting patients and can be displayed in details as a pictorial essay. All cases were paired with cytological or/and histological confirmation. Both SE and ARFI imaging were performed in benign and malignant thyroid nodules in order to depict the hardness of the examined lesion. SE provides qualitative assessment of the tissue hardness. Strain ratio consist a quantification of this qualitative type of elastography. ARFI imaging is divided into two types: a) Virtual Touch Tissue Imaging (VTI) which provides the relative stiffness in qualitative way in the selected region of interest on a gray scale image and b) Virtual Touch Tissue Quantification (VTQ) which expresses the shear wave speed in solid materials as numeric values and describes quantitatively the hardness of tissue.
