Contrast-enhanced ultrasound for prostate cancer imaging

Prostate cancer is the number one non-skin malignancy of males in Western countries. Analysis of the care cycle for prostate cancer patients indicates the lack of an accurate screening test, and the lack of a widely available and reliable imaging method for local tumors. This article presents a new approach to imaging localized prostate cancer: contrast-enhanced ultrasonography (CEUS). The method is based on the visualization of microvessel density by microbubble contrastagents. In this pilot project, contrast-enhanced ultrasound (CEUS) imaging was correlated with histology. The results indicate that changes in theperfusion characteristics revealed by CEUS correlate with malignant tissue.
