Shear wave elastography for solid breast masses evaluation: Quantitative measurement of mean elasticity value and elasticity ratio.

Purpose: Shear wave elastography (SWE), an ultrasonographic technique to measure the elasticity of mass lesions to evaluate breast mass. This study aimed to find out the cutoff values identifying breast malignancy using the mean elasticity (E-mean) and elasticity ratio (E-ratio) of breast masses.

Methods: This retrospective study included women underwent SWE and US-guided biopsy of breast masses.

Comparison of the diagnostic accuracy of K-TIRADS and EU-TIRADS guidelines for detection of thyroid malignancy on ultrasound.

Introduction: This retrospective study compared the diagnostic accuracy of histopathologically proven thyroid nodules between the Korean Thyroid Imaging Reporting and Data System (K-TIRADS) and the European Thyroid Imaging Reporting and Data System (EU-TIRADS) guidelines for the management of thyroid nodules characterized by ultrasonography.

Material And Methods: For thyroid nodules resected from 2018 to 2021 at our institution, static ultrasound images of each nodule were reviews and stratify into both systems. Agreement between above two classifications was compared based on histopathological results.
