Brian, Paul,

Conventionally, nuclear imaging refers to the use of injected or
ingested X-ray producing radioactive material to examine certain body
systems in detail in X-ray images. Nuclear medicine is the more
general term for the use of radioactive material in the medical field.

Nuclear Magnetic Resonance Imaging (NMRI or just MRI) involves
tweaking atomic nuclei with magnetic fields, but it's not part of
nuclear medicine.

The use of radioactive isotopes in medicine is very much a
risk/benefit analysis, as they do carry risks.
