ABSTRACT
The mammographic or physical evaluation of breast parenchymal abnormalities in the presence of radiopaque implants or silicone injections is difficult; mammography often fails to discriminate between breast cancer and a radiopaque dense breast. Although the sonographic evaluation of a palpable mass in an augmented breast may be impaired by the presence of posterior acoustic shadowing, the modality may be helpful in evaluating such masses, and dynamic contrast-enhanced MR imaging facilitates differentiation. FDG-PET is a possible alternative diagnostic tool for the evaluation of parenchymal lesions under these circumstances, but its drawbacks are its high cost and limited availability. The sensitivity and specificity of both FDG-PET and MRI can be improved by correlating their findings with those of radiological studies, and through an awareness of potential false-negative and false-positive causes.
