    Area of Science:

    • Medical Imaging
    • Biophysics
    • Biochemistry

    Background:

    • Nuclear Magnetic Resonance (NMR) is a non-invasive imaging technique.
    • It utilizes magnetic fields and radio frequencies to detect signals from atomic nuclei.
    • Naturally abundant nuclei like hydrogen (1H), phosphorus (31P), and carbon (13C) are key targets.

    Purpose of the Study:

    • To explain the principles of NMR and NMR imaging.
    • To explore NMR's capabilities in assessing anatomical and functional information.
    • To discuss the applications of NMR in medicine and biology.

    Main Methods:

    • Employing static and radio frequency (RF) magnetic fields to excite nuclear magnetic field emission.
    • Utilizing magnetic field gradients for spatial encoding of emissions.
