CEST 2 RF METHOD FOR RF EXCITATION WITH TWO RESONANCE FREQUENCIES TO DETECT THE CEST EFFECT BY MEANS OF A MAGNETIC RESONANCE SYSTEM

摘要

To detect the CEST effect by a magnetic resonance system, an RF excitation method with two resonant frequenciesThe present invention is characterized in that two resonance frequencies f (t) for detecting the CEST effect by the magnetic resonance system 5_One, F₂(25). Thereby, the RF excitation 25 is configured such that the first part of the RF excitation 25 by the first resonance frequency f1 of the two resonance frequencies is implemented by the first RF antenna 4, The first RF antenna 4 and the second RF antenna 4 of the magnetic resonance system 5 in that the second portion of the RF excitation 25 by the two resonant frequency f2 is implemented by the second RF antenna 4 '' Is realized with the aid of the antenna 4 ''.
