Contrast-enhanced ultrasound in the characterisation of breast masses: utility of quantitative analysis in comparison with MRI.

Objective: To evaluate the reliability of contrast-enhanced ultrasound quantitative analysis (CE-US) in characterizing breast lesions, in comparison with MRI.

Materials: Thirty-nine patients with breast lesions BI-RADS 3-5 at US or mammography underwent CE-US and MRI. All lesions underwent histological and quantitative enhancement evaluation with both imaging methods.
