Abstract A multi-frequency imaging radio frequency (RF) coil operational at three or more different frequencies, with a shifting frequency loop structure proximate the coil and switchably coupled to provide different frequencies when the loop structure is coupled to the coil. In one embodiment one of the frequencies is a proton frequency, one is a sodium frequency, and one of the frequencies is a carbon frequency. One example involves imaging examinations using hyperpolarized compounds. L'invention concerne une bobine de radiofréquence (RF) d'imagerie multifréquence opérationnelle à trois fréquences différentes ou plus, avec une structure de boucle de fréquence de changement à proximité de la bobine et couplée de manière commutable pour fournir des fréquences différentes lorsque la structure de boucle est couplée à la bobine. Dans un mode de réalisation, l'une des fréquences est une fréquence protonique, l'une des fréquences est une fréquence de sodium et l'une des fréquences est une fréquence de carbone. Un exemple implique des examens d'imagerie à l'aide de composés hyperpolarisés.
