The present invention relates to a combined positron emission tomography-magnetic resonance imaging apparatus, which comprises a positron emission tomography apparatus (3) having at least one radiation detector (4), and a magnetic resonance imaging apparatus having at least one gradient coil (6) and a high-frequency antenna device (8). In order to prevent mechanical vibration being induced in the PET gantry by the gradient coil, the combined position emission tomography-magnetic resonance imaging apparatus according to the present invention is developed in that a first molding part (7) is provided, the surface of which coincides with the inner shell (9) of the at least one gradient coil (6), and a second molding part (10) is provided, the surface of which coincides with the outer shell (11) of the radiation detector (4), the distance between the two shells (9, 11) is virtually constant over the circumference of the shells, and a vacuum seal (13) is respectively arranged along at least a first circumferential
