ABSTRACT:
A stereotactic auxiliary attachment for a nuclear magnetic resonance tomography apparatus for use in conducting mammographic examinations wherein a needle localization of a breast mass or needle marking of a breast mass are implemented with high precisions includes two parallel compressions plates mounted so as to be displaceable relative to one each other, and between which an examination subject such as breast, can be compressed. At least one of the plates has a reception coil of the magnetic resonance tomography apparatus allocated thereto, and at least one of the plates has holes therein for the introduction of a biopsy or marking needle. One of both of the plates can be provided with markings which are identifiable in the magnetic resonance image (tomogram).
