ABSTRACT:
The invention relates to a magnetic resonance examination apparatus, comprising a coil system for MR mammography which has a particularly attractive signal-to-noise ratio. It comprises a first coil system (11) which comprises conductor loops which are merely inductively coupled to one another and which are provided on the surface of a cylinder in parallel planes, one of the loops being connectable to an input (22) of a receiving device (20). It also comprises a second coil system (12, 13) which is constructed as a surface coil and which is arranged at the end face of the first coil system (11) and can be connected to a further input (21) of the receiving device (20).
