摘要:
A mammography antenna arrangement for magnetic resonance examinations of the female breast has first and second conductor loop pairs, each of which is formed by two saddle-shaped conductor loops lying opposite one another and between which an essentially cylindrical examination space, having a receptacle opening, is located. The two conductor loop pairs are rotationally offset by 90.degree. relative to one another in the circumferential direction. A capacitive element is connected in a part of each conductor loop that faces away from the receptacle opening.
