The statistical analysis was performed with the SPSS statistical package (Version 19.0, SPSS Chicago, IL, United States) and MedCalc 11.4.2.0 software (MedCalc Software, Ostend, Belgium). The quantitative data were expressed as the mean ± standard deviation. The Student's t-test was used for comparing the groups. The χ2 test or Fisher's exact test was used to compare categorical data. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy were calculated through a comparison with the pathological findings. A receiver operating characteristic (ROC) curve analysis was used to compare CEUS, ES, and CUS. A P < 0.05 was considered statistically significant.
