I knew someone would ask this sooner or later! In short, it is similar to radiology with a few key differences:
- Nuc Med is used more for looking at functional anatomy, whereas radiology is almost always just anatomy, think of it as they take an x-ray of a bone, see a crack and say its broken, I use a particular chemical that is attached to a short lived radioactive particle that is used by bones when they remodel - so I see it has gone to an area of a suspected fracture and can see new bone is forming and thus deduce it is fractured.
- Radiology usually sends radioactive particles through people and then images the particles that have passed through and they make pictures based on the difference densities of what its gone through - bone, soft tissue etc. Whereas, we (usually) inject radioactive particles into you, which localise or are used by a particular part of the body, and we make pictures based on where we detect the particles have gone to.
- Radiology is usually just for diagnostic purposes, Nuc Med is used diagnostically and in some therapy situation.
Now the REAL differences...
- Radiology deal with blood and guts, I usually don't have to
- They often have to do shift work and call ins, I don't as much - although the dept I'm going to does do a bit.
- Their patients often have to get at least partially undressed, ours don't!
- They do enemas, I don't!
So similar in a few ways, and are often complementary to each other, but still quite different.
The confusing bit:
- Both can be licensed to do CT's (aka CAT scans), but we usually do them as part of a Nuc Med procedure, as opposed to on its own (we make pretty pictures showing a body part functioning, and overlay it onto a high quality CT image)
- Both can be trained to do MRI
- Both can be trained in Ultrasound.
So, that's it in a pretty generalised sense! It's good fun, and I enjoy being able to talk to patients and find out their backgrounds and generally help make a difference to their outcomes.
And Chops, stop trying to blow my cover!

But speaking of the Landy, I gave her some TLC today by letting her go to Modern Motors in Dungog, and they gave her timing, and injector pump a looking over and a few little adjustments made

- its a whole new joy to drive.
