Abstract

A local coil arrangement for magnetic resonance applications has a base body in which at least one local coil is arranged. An excitation signal to excite an examination subject to emit a magnetic resonance signal can be emitted by the local coil and/or a magnetic resonance signal emitted by the examination subject can be received by means of said local coil. At least one volume region is present in the base body, in which an amount of a substance is located that can be excited by means of the coil or another coil so as to emit a magnetic resonance signal. A shielding is arranged in the base body. The shielding can be controlled so as to either shield or not shield the volume region depending on the control state, so that the volume region is occluded or visible with regard to magnetic resonance applications.
