Abstract

Dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) and contrast-enhanced ultrasound (CEUS) analyse tissue vascularization. We evaluated if CEUS can provide comparable information as DCE-MRI for the detection of prostate cancer (PCa) and prediction of its aggressiveness. A post-hoc evaluation of 92 patients was performed. In each patient CEUS and DCE-MRI parameters of the most suspicious lesion identified on MRI were analysed. The predictive values for discrimination between benign lesions, low-/intermediate- and high-grade PCa were evaluated. Results of targeted biopsy served as reference standard (benign lesions, n=51; low- and intermediate-grade PCa [Gleason grade group 1 and 2], n=22; high-grade PCa [ae<yen> Gleason grade group 3], n=19). In peripheral zone lesions of all tested CEUS parameters only time to peak (TTPCEUS) showed significant differences between benign lesions and PCa (AUC 0.65). Of all tested DCE-MRI parameters, rate constant (K-ep) was the best discriminator of high-grade PCa in the whole prostate (AUC 0.83) and in peripheral zone lesions (AUC 0.89). DCE-MRI showed a superior performance for detection of PCa and prediction of its aggressiveness. CEUS and DCE-MRI performed better in peripheral zone lesions than in transition zone lesions. aEuro cent DCE-MRI gathers information about vascularization and capillary permeability characteristics of tissues. aEuro cent DCE-MRI can detect PCa and predict its aggressiveness. aEuro cent CEUS also gathers information about vascularization of tissues. aEuro cent For detection of PCa and prediction of aggressiveness DCE-MRI performed superiorly. aEuro cent Both imaging techniques performed better in peripheral zone lesions.
