Abstract: The present invention describes a method in the field of a magnetic resonance imaging (MRI), said method comprising creating an object MR image in an MRI simulator unit: performing an image/parameter comparison of the object MR image and parameter(s) thereof with a second MR image and/or a corresponding set of parameters functioning as a reference: wherein the comparison is based on at least comparing the anatomical position of the object MR image and/or parameter(s) thereof and the second MR image and/or the corresponding set of parameters, said method also comprising providing automatic feedback on the image/parameter comparison and providing the same in a user interface of the MRI simulator unit.

Abstract: An isolated peptide or peptidomimetic, comprising an ?-nemertide moiety, wherein a) said ?-nemertide moiety has a sequence according to SEQ ID NO: 1; or b) said ?-nemertide moiety has a sequence differing from SEQ ID NO:1 by residue substitutions, deletions or insertions numbering no more than 9 in total. Medical, pest control and research uses thereof.
