Low-cost low-field NMR and MRI: Instrumentation and applications. [PDF]

open access: yesJ Magn Reson, 2020
While NMR and MRI are often thought of as expensive techniques requiring large institutional investment, opportunities for low-cost, low-field NMR and MRI abound. We discuss a number of approaches to performing magnetic resonance experiments with inexpensive, easy to find or build components, aimed at applications in industry, education, and research ...

Low-Cost Purpose-Built Ultra-Low-Field NMR Spectrometer. [PDF]

open access: yesAnal Chem
Low-field NMR has emerged as a new analytical technique for the investigation of molecular structure and dynamics. Here, we introduce a highly integrated ultralow-frequency NMR spectrometer designed for the purpose of ultralow-field NMR polarimetry of hyperpolarized contrast media. The device measures 10 cm × 10 cm × 2.0 cm and weighs only 370 g.

Understanding water properties in tumorous murine cells using field-cycling NMR relaxometry [PDF]

open access: yesScientific Reports
The fixed high magnetic fields (1–7 Tesla) used for magnetic resonance imaging produce resolution suitable for oncology but image contrast is insufficient to determine tumour stage.
