1. A data-processing method for analyzing a body-part, the method including the steps of: providing a parametric map including a plurality of parameter values each one characterizing a corresponding location of the body-part, determining a saturation value partitioning an ordered sequence of processing parameter values, corresponding to processing locations into a first subset and a second subset consisting of a number of the processing parameter values being determined according to a predefined auto-scaling percentage, generating an auto-scaled map including, for each processing location, an auto-scaled value being equal to: a) the corresponding processing parameter value if included in the second subset, or b) the saturation value if the corresponding processing parameter value is included in the first subset, determining at least one statistical indicator of at least one distribution of a plurality of the auto-scaled values corresponding to analysis locations included in the processing locations, and displaying a representation of said at least one statistical indicator to provide an indication of a condition of an analysis region of the body-part defined by the analysis locations.
