Abstract:
1. An examination apparatus for examination of an object of interest, the examination apparatus comprising: an acquisition unit configured to determine a first contrast agent concentration after a first contrast agent application and before a second contrast agent application and to determine a second contrast agent concentration after the second contrast agent application, resulting in a series of determined contrast agent concentration values as a function of an overall contrast agent application value, wherein application of the contrast agent is absent between the first contrast agent application and the second contrast agent application; and a determination unit configured for: fitting a linear slope to the series of determined contrast agent concentration values as the function of the overall contrast agent application value; monitoring deviations of a linearity of the slope; and determining a leakiness of the object of interest based on the monitored deviations; wherein the fitting is performed based on a weighting of the first determined contrast agent concentration with a corresponding first error bar and a weighting of the second determined contrast agent concentration with a corresponding second error bar; and wherein the examination apparatus is a magnetic resonance examination apparatus.
