2D-FT Nuclear magnetic resonance imaging (2D-FT NMRI), or two-dimensional Fourier transform nuclear magnetic resonance imaging (NMRI), is primarily a non-invasive imaging technique most commonly used in
biomedical research and medical radiology to visualize structures and functions of the living systems and single
cells. The physical principle[1] is essentially the same in N(MRI), nuclear magnetic resonance, FT (NMR)
spectroscopy, topical NMR, or even in electron spin resonance (ESR); however, the details are significantly different
at present for ESR, as only in the early days of NMR the static magnetic field was scanned for obtaining spectra, as it
is still the case in many ESR spectrometers. NMRI, on the other hand, often utilizes a linear magnetic field gradient to obtain an image that combines the visualization of molecular structure and dynamics. It is this dynamic aspect of NMRI, as well as its highest sensitivity for the 1H nucleus that distinguishes it very dramatically from X-ray CAT
scanning that 'misses' hydrogens because of their very low X-ray scattering factor.
