For further reading:
Bernstein, Matt A., Kevin F. King, and Xiaohong Joe Zhou. Handbook of MRI Pulse Sequences. Boston, MA: Academic Press, 2004. ISBN: 9780120928613.
Good reference on wide range of MRI topics.
Hore, P. J. Nuclear Magnetic Resonance. New York, NY: Oxford University Press, 1995. ISBN: 9780198556824.
Good introduction to NMR phenomenon and easy to read.
Hore, P. J., J. A. Jones, and S. Wimperis. NMR: The Toolkit. New York, NY: Oxford University Press, 2000. ISBN: 9780198504153.
Covers spectroscopy mostly.
Abragam, A. The Principles of Nuclear Magnetism. New York, NY: Oxford University Press, 1983. ISBN: 9780198520146.
A classic, but very dense and not all that easy to read.
Slichter, C. P. Principles of Magnetic Resonance. 3rd ed. New York, NY: Springer-Verlag, 1992. ISBN: 9780387501574.
Also a classic, a bit easier to read than Abragam.
