Abstract

In an apparatus for the recognition of pneumothorax using thorax MR exposures, an evaluation device segments the image of the rib cage, including its surroundings, and characterizes a zone detected between rib cage and lung, preferably in the exhaled condition, that has an MR signal elevated by a prescribed safety margin compared to the noise signal in air.
