Abstract EN
Objectives.
To evaluate virtual touch tissue imaging quantification (VTIQ) as a new elastography method concerning its intra- and interexaminer reliability and its ability to differentiate benign from malignant breast lesions in comparison to and in combination with ultrasound (US) B-mode breast imaging reporting and data system (BI-RADS) assessment.
Materials and Methods.
US and VTIQ were performed by two examiners in 103 women with 104 lesions.
Intra- and interexaminer reliability of VTIQ was assessed.
The area under the receiver operating curve (AUC), sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of BIRADS, VTIQ, and combined data were compared.
Results.
Fifty-four of 104 lesions were malignant.
Intraexaminer reliability was consistent, and interexaminer agreement showed a strong positive correlation (r=0.93).
The mean VTIQ values in malignant lesions were significantly higher than those in benign (7.73 m/s ± 1.02 versus 4.46 m/s ± 1.87; P<0.0001).
The combination of US-BIRADS with the optimal cut-off for clinical decision making of 5.18 m/s yielded a sensitivity of 98%, specificity of 82%, PPV of 86%, and NPV of 98%.
The combination of BIRADS and VTIQ led to improved test validity.
Conclusion.
VTIQ is highly reliable and reproducible.
There is a significant difference regarding the mean maximum velocity of benign and malignant lesions.
Adding VTIQ to BIRADS assessment improves the specificity.
