In this paper we present a specially tailored volumetric visualization for MRI data acquired for monitoring Crohn's Disease. The aim is to provide the physicians with an alternative to reviewing all slices of the data separately. To be able to highlight the features important for the monitoring, we employ dynamic-contrast enhanced MRI (DCE-MRI) data. The interesting features exhibit speciﬁc time-intensity curves (TIC). We determine for each position how good the local TIC resembles a typical curve of inﬂamed tissue using a derived parameter we call normalized integral. The result is then used to emphasize those locations in the volumetric visualization.
