"...the name "Magnetic Resonance Imaging" is at least partly due a fear that this imaging technique involved nuclear radiation."

Absolutely correct.

"Unless someone is a chemist who was completely blind from birth, I can't imagine how a chemist can analyze the various possibilities in a molecule's structure from any chemical formula without using some sort of image."

Well, yes---but it is the CHEMIST who does the necessary "imaging", and not the INSTRUMENT.

True enough after he eyeballs the images of nuclear magnetic spectra.

FIG. 4. 1D 1H NMR spectra of A12-b (A) and B12-b (B). Anomeric and other structural reporter proton resonances are indicated by roman numerals corresponding to the position of the residue in the sequence as shown in the formulae.
