| N/A – not applicable. Variables are shown as frequency (percentage). * Comparison with respect to biopsies/histopathology. BI-RADS – The Breast Imaging-Reporting and Data System. 0 – Inconclusive results; 1 – tumor was absent; 2 – benign tumor; 3 – probably benign; 4 – suspicious abnormality; 5 – highly suggestive of malignant. Fischer’s exact test or Chi-square independence test was used for statistical analysis. ** Significant difference with respect to mammography. | |||||||||
