“Does nuclear medicine and radiology work hand in hand?”

yes.

Yes, it definitely does. They’re both imaging modalities, but radiology evaluates anatomical structures, i.e., bones, organs, muscles, etc., via radiation that the camera produces which subsequently is transmitted through the patient. Nuclear medicine evaluates a particular function. By administering a substance that’s already in our bodies, or one very similar to it,
labeled with a very small amount of a radioactive isotope the function of a particular organ system can be evaluated. This is done by analyzing the pictures made when the radioactive isotope decays, releasing energy that is detected by the camera. Anatomical imaging is often done in conjunction with functional imaging.
Hope this helps!

yes

Nuclear Medicine is now generally a division of nuclear medicine. It is called nuclear because the photons emitted for Imaging come from the nucleus. Thus we image the emissions of photons. X-rays come from the electron shell. Imaging is done through transmission. That is the x-rays pass through soft tissues at different rates of absorption. Nuclear medicine generally looks at physiology and radiology at anatomy. Many times the images are combined as in a PET/CT scan. The functional image is overlaid atop the anatomical one. The answer to your question is that there is a strong relationship between other branches of radiology and nuclear medicine.
