Abstract
Background: To assess and compare the role of Contrast-Enhanced Spectral Mammography (CESM) versus Contrast-Enhanced Magnetic Resonance Imaging (MRI) in the evalu-ation of BI-RADS 3 and BI-RADS 4 breast lesions diagnosed by Digital mammography and correlate the findings with the pathology results.
Material and Methods: CESM and MRI examinations were performed in 54 female patients who had BI-RADS 3 or BI-RADS 4 breast lesions described in Digital mammog-raphy. Each detected lesion was specified according to BI-RADS classification, localisation and lesion size on both modalities. The imaging findings were compared to the pa-thology results.
Results: 58 lesions were detected in 54 cases. 41/58 of the lesions were pathologically diagnosed as malignant and 17/58 were benign. CESM showed lower sensitivity for breast cancer detection but higher specificity compared to MRI. In terms of lesion size measurement, the best correlation with pathology was found for MRI.
Conclusion: Each of the two modalities (CESM and MRI) is a useful diagnostic tool in the evaluation of BI-RADS 3 and BI-RADS 4 breast lesions. CESM showed lower sensitivity for breast cancer detection but higher specificity compared to MRI.
