Abstract: One embodiment relates to a method for providing image data of a hollow organ. The method includes applying a first contrast agent to a lumen of the hollow organ, to obtain a contrast agent filling of the lumen; applying a second contrast agent to a blood vessel system, the blood vessel system supplying a wall of the hollow organ, the second contrast agent having a different absorption spectrum than the first contrast agent; generating spectrally resolved computed tomography data of an examination area, the examination area including the hollow organ; calculating first image data indicative of a presence of the first contrast agent and second image data indicative of a presence of the second contrast agent by applying a material separation algorithm onto the spectrally resolved computed tomography data; and providing the image data of the hollow organ including the first image data and the second image data.

Abstract: A method for determining a quantitative result CT parameter map in a region of interest of an object under examination is described. The method includes acquiring a sequence of quantitative input CT parameter maps for at least two predetermined times, the sequence being generated by a contrast-enhanced spectral multiphase CT of the region of interest; receiving a sequence of contrast-enhanced MRI image datasets, the MRI datasets having a higher temporal resolution than the sequence of input CT parameter maps; determining a relation between the MRI image datasets and the input CT parameter maps; and determining the result CT parameter map based on the determined relation and the MRI image datasets for at least one additional time, the at least one additional time being different from the predetermined time.

Abstract: A method for providing thermal conductivity data relating to an anatomical structure, comprises: receiving first spectral computed tomography data relating to the anatomical structure; calculating a fat map of the anatomical structure and a water map of the anatomical structure based on the first spectral computed tomography data; calculating the thermal conductivity data relating to the anatomical structure based on the fat map and the water map; and providing the thermal conductivity data.

Abstract: A method is for setting a contrast of a multi-energy CT image representation. In an embodiment of the method, a plurality of multispectral image datasets of an examination region of a patient are received. Furthermore, an automated identification of a structure to be examined is achieved based upon the multispectral image datasets and an automated combining of the differently weighted multispectral image datasets is accomplished such that the contrast between the structure to be examined and its environment is improved compared to a uniform weighting. Further, a multi-energy CT imaging method is described. An image setting device is also described. In addition, a computed tomography system is described.

Abstract: In a method for display of at least one medical finding, at least one part of a body of a patient is shown on a display medium in a body view. A localization in the body of the patient is associated with each finding, and the localizations are marked at a point in the body view corresponding to the localization. The display medium is interactively operable, and a data set associated with the corresponding finding is displayed on the display medium by interaction with a marked localization.
