Abstract:
1. A water-soluble paramagnetic substance that reduces a magnetic resonance relaxation time of a coolant used in a magnetic resonance imaging system, wherein the coolant is arranged to flow along a circumferentially extending coolant line arranged to dissipate a thermal load produced by one or more components of the magnetic imaging system, the one or more components including: at least a radio frequency coil and/or one or more gradient coils which are arranged to be electromagnetically shielded from the coolant line by a metallic shield except at an unshielded region defined by an oblique recess in an annular structure configured for receiving a patient, wherein the magnetic resonance imaging system is configured to generate an image of an organ or a region of the body of the patient located at least in part within the unshielded region, wherein the image consists of anatomical features of the organ or region of the body of the patient, whereby a resulting reduction of the magnetic resonance relaxation time of the coolant reduces formation of artifacts in the image of the organ or a region of the body of the patient located at least in part within the unshielded region defined by the oblique recess in the annular structure configured for receiving the patient.
