Prostate cancer (PCa) diagnosis still relies on systematic biopsy due to the insufficient reliability of imaging techniques. In this work, we introduce a new method to quantify contrast agent convective dispersion (D) and velocity (v) in a three-dimensional dynamic contrast-enhanced ultrasound (3D DCE-US) recording. First, the concentration gradients of the data are established using Gaussian derivatives...
Although prostate cancer (PCa) is the most common non-cutaneous form of cancer among Western men, available diagnostic imaging methods are not yet sufficiently reliable to avoid systematic biopsy. In this work, we aim at improving the accuracy of transrectal dynamic contrast-enhanced ultrasonography (DCE-US) for PCa localization by combining local perfusion and dispersion parameters. To this end,...
Prostate cancer is the form of cancer with the highest incidence in men. The invasiveness or low specificity of available diagnostics hampers a timely use of efficient focal therapies. New imaging techniques are therefore needed for an early prostate cancer localization. We propose a new ultrasound imaging method for prostate cancer localization based on quantification of the (intravascular) local...
