A method for a semi-automatic detection whether an MR examination of a person is approved with a predetermined MR system, which MR system includes at least one coil (14, 16, 18) for generating a magnetic field, wherein the method comprises the following steps: - Step 1: providing information whether and which contra-indication for such an MR examination is present for the person via a user interface, wherein the cause of the contra-indication is an implant; - Step 2: providing information about a location of the cause of the contra-indication within the person; - Step 3: a determination of a position of this cause during the MR examination of said person with respect to the at least one coil (14, 16, 18); - Step 4: a determination of at least one characteristic parameter of the magnetic field generated by said coil (14, 16, 18) at said position of the cause during the MR examination, wherein the characteristic parameter of the magnetic field generated by the at least one coil is a magnetic field gradient, wherein the characteristic parameter is determined by clicking the location of the implant on a gradient plot of the magnetic field gradient on the user interface and entering a maximum value from a label of the implant into the user interface; - Step 5: an automatic check, whether the MR examination is approved for the combination of the determined cause of the contra-indication and the determined characteristic parameter of the magnetic field at the position of said cause by comparing the magnetic field gradient and the maximum value; and - Step 6: an automatic release of the MR examination of the person in case the MR examination is approved and an automatic blocking of the MR examination of the person in case the MR examination is not approved; - Step 1: providing information whether and which contra-indication for such an MR examination is present for the person via a user interface, wherein the cause of the contra-indication is an implant; - Step 2: providing information about a location of the cause of the contra-indication within the person; - Step 3: a determination of a position of this cause during the MR examination of said person with respect to the at least one coil (14, 16, 18); - Step 4: a determination of at least one characteristic parameter of the magnetic field generated by said coil (14, 16, 18) at said position of the cause during the MR examination, wherein the characteristic parameter of the magnetic field generated by the at least one coil is a magnetic field gradient, wherein the characteristic parameter is determined by clicking the location of the implant on a gradient plot of the magnetic field gradient on the user interface and entering a maximum value from a label of the implant into the user interface; - Step 5: an automatic check, whether the MR examination is approved for the combination of the determined cause of the contra-indication and the determined characteristic parameter of the magnetic field at the position of said cause by comparing the magnetic field gradient and the maximum value; and - Step 6: an automatic release of the MR examination of the person in case the MR examination is approved and an automatic blocking of the MR examination of the person in case the MR examination is not approved;
