High-Field Detection of Biomarkers with Fast Field-Cycling MRI: The Example of Zinc Sensing. [PDF]
Chemistry, 2019 AbstractMany smart magnetic resonance imaging (MRI) probes provide response to a biomarker based on modulation of their rotational correlation time. The magnitude of such MRI signal changes is highly dependent on the magnetic field and the response decreases dramatically at high fields (>2 T).

Signal averaging in cryogenic fast-field-cycling NMR experiments [PDF]
Scientific ReportsThe spin-lattice relaxation time constant $$T_1$$ characterizes the equilibration of a spin system in a magnetic field with its environment, the lattice. Fast-field-cycling (FFC) relaxometry is dedicated to $$T_1$$ measurements at low field.

Joint multi-field T<sub>1</sub> quantification for fast field-cycling MRI. [PDF]
Magn Reson Med, 2021 PurposeRecent developments in hardware design enable the use of fast field‐cycling (FFC) techniques in MRI to exploit the different relaxation rates at very low field strength, achieving novel contrast. The method opens new avenues for in vivo characterizations of pathologies but at the expense of longer acquisition times.

R 1 dispersion contrast at high field with fast field-cycling MRI [PDF]
Journal of Magnetic Resonance, 2018 Contrast agents with a strong $R_1$ dispersion have been shown to be effective in generating target-specific contrast in MRI. The utilization of this $R_1$ field dependence requires the adaptation of a MRI scanner for fast field-cycling (FFC). Here, we present the first implementation and validation of FFC-MRI at a clinical field strength of 3 T.

Application of CPMG acquisition in Fast-Field-Cycling relaxometry [PDF]
Microporous and Mesoporous Materials, 2018 Abstract The possibility and limits for applying the CPMG sequence during the acquisition period of Fast-Field-Cycling relaxometry measurements were investigated. Fluctuations of the acquisition field strength were quantified and related to the signal phase fluctuations they cause in CPMG measurements.

Environmental NMR: Fast-field-cycling Relaxometry [PDF]
, 1996 Fast-field-cycling (FFC) NMR relaxometry deals with the variation of the spin–lattice relaxation times (T1) in a complex system, as the strength of the applied magnetic field is changed. Information about molecular dynamics can be achieved. Until now, only model theories for FFC NMR relaxometry have been developed for polymer and material sciences ...
