Which of the statements below is false?
A. At a magnetic field strength of 1.5 T, the NMR resonance frequency of 1H is 63.87 MHz.
B. NMR is capable of detecting very small population differences because it is a resonance technique.
C. If Helium nuclei were present in our bodies, they would be the ideal nuclrei for MRI, because helium nuclei have a net spin of zero.
D. Magnetic resonance imaging (MRI) primarily images the NMR signal from the hydrogen nuclei.
E. Different chemical environments generate different local magnetic fields at the locations of the nuclei, and therefore slightly shift the NMR resonance frequency.
