The diagnostic performance of ultrasound and mammography in evaluating screening ultrasound detected breast lesions after adding elastography to ultrasound

Abstract

Purpose To determine the diagnostic performance of ultrasonography (US) and mammography in the differential diagnosis of breast lesions after adding different types of elastography to US. Materials and Methods This institutional review board-approved study included 316 US detected masses in 280 women between January 2016 and July 2018. All these lesions were evaluated with conventional ultrasonography, elastography and mammography prior to biopsy or surgery. Each lesion was underwent evaluated with three type of elastography including elasticity imaging (EI), virtual touch tissue imaging (VTI) and Virtual Touch Imaging Quantification (VTIQ). US breast Imaging-Reporting and Data System (BI-RADS) category 4A lesions would be downgraded if on positive findings on elastography. Diagnostic performances were calculated for mammography, US elastography and the combination of US and elastography. Results Of 316 breast lesions, 134 were malignant. The sensitivity of conventional US (100%) was significantly higher than that of mammography (84.6%, p Conclusion The combinations of US and EI, VTI improved the specificity without sacrificing sensitivity which showed a better diagnostic performance in the differential diagnosis of breast lesions than mammography
