The Larmor frequency as a probe of tissue magnetic microstructure
Magnetic Resonance imaging (MRI) is a powerful non-invasive imaging technique used in radiology. In MRI, oscillations of the body's water molecules are induced by a strong magnetic field and radio waves. The number of oscillations per second defines the Larmor frequency. In addition, this magnetic field also makes MRI particularly sensitive to how the body's tissues become magnetized by the MRI scanner, as it can produce small changes to the Larmor frequency of the body's water molecules reflecting the tissue composition. This "magnetic susceptibility" may be a useful biomarker for understanding neurodegenerative diseases.
The connect between the MRI signal and the body's magnetic tissue microstructure is investigated in a new PhD project at Aarhus University, Health. The study was carried out be Anders Dyhr Sandgaard, who is defending his dissertation on May 31, 2023.
The findings contributes to our understanding of how the MRI Larmor frequency may be used to gain insights into the magnetic tissue - orders of magnitudes below the typical image resolution used clinically.
