Diffusion-Weighted Imaging of Mucinous Carcinoma of the Breast: Evaluation of Apparent Diffusion Coefficient and Signal Intensity in Correlation With Histologic Findings

Abstract

Mucinous carcinoma can be clearly differentiated from other breast tumors on the basis of ADC. The low signal intensity of mucinous carcinoma on diffusion-weighted images appears to reflect the presence of mucin and low cellularity. High signal intensity on diffusion-weighted images may reflect the presence of fibrovascular bundles, increased cell density, or a combination of these features.
