A magnetic resonance (MR) probe head comprises a detecting device ( 3 ) with at least one antenna system which is cryogenically cooled by a cooling device, a cooled preamplifier ( 16 ) in a preamplifier housing ( 15 a, 15 b) which is spatially separated from the detecting device ( 3 ), and a thermally insulating connecting means via which the detecting device ( 3 ) and the preamplifier housing ( 15 a, 15 b) are connected, wherein the connecting means ( 15 c) comprises at least one cooling line ( 9 a, 9 b, 53 a, 53 b) for supplying and/or returning a cooling fluid, and at least one RF line ( 10, 52 ) for transmitting electric signals. The connecting means ( 15 c), including its RF and cooling lines ( 10, 52, 9 a, 9 b, 53 a, 53 b), can be separated from the preamplifier housing ( 15 a, 15 b) by a coupling. The MR probe head is an open system which can be used in a universal fashion through use of different measuring inserts. The system can be expanded for further measuring configurations at little cost and can be easily handled in a time-saving fashion with an optional arrangement having a flexible connecting line.
