Disclosed is a scanning device for magnetic resonance imaging for medical diagnostics, more particularly for dental-medical diagnostics or ENT diagnostics, having a main magnet for generating a static main magnetic field having a homogeneous region, and having at least one transmitting and/or receiving coil for emitting and/or receiving a radio-frequency magnetic field. Provision is made, in particular, for the main magnet to be formed by two poles of magnetically opposite polarities at the end side, such that the static main magnetic field generated by the two poles at the end sides thereof, including the homogeneous region, projects beyond the end sides of the poles.
