A method and a device are disclosed for providing a segmented volume data record for a virtual colonoscopy, the volume data record having image information relating to the intestines of a creature, which intestines have been labeled by a first and a second contrast agent. In at least one embodiment, voxels representing the first contrast agent, voxels representing stool remains labeled by the second contrast agent and voxels representing intestinal tissue are segmented, the segmentation taking place in a volume data record recorded of the body region of the creature having the intestines, which have been labeled by a first and a second contrast agent. In at least one embodiment, at least sections of the intestinal wall are displayed on the basis of the segmentation in the virtual colonoscopy, even if these sections of the intestinal wall are, in the segmented volume data record, covered by stool remains labeled by the second contrast agent. Further, a computer program product having a computational program for carrying out the method is also disclosed.
