Singulett‐Kontrast‐Magnetresonanztomographie: Freisetzung der Hyperpolarisation durch den Metabolismus**

Abstract: Hyperpolarisationsverstärkte Magnetresonanztomographie kann zur Untersuchung biomolekularer Prozesse im Körper verwendet werden, erfordert aber die Verwendung von Hetero‐Kernen wie 13C, 15N oder 129Xe. Hier stellen wir eine neue Art der Hyperpolarisierten Protonen Bildgebung vor, bei der die hyperpolarisierte Spinordnung in einem nicht magnetischen und langlebigen korrelierten (Singulett‐) Zustand eingeschlossen ist und nur durch eine spezifische biochemische Reaktion für die Bildgebung freigesetzt wird. In di… Show more

“…Commonly the inequivalence is caused by a chemical shift difference between the two protons that is greater than their mutual J-coupling. However, if the protons are close to chemical or magnetic equivalence, the non-magnetic singlet state remains close to an eigenstate, and either electromagnetic pulses [188] or further chemical reactions [189,190] are needed to release the singlet order to generate observable hyperpolarized signals.…”
