Can someone compare and contrast Nuclear Medicine and PET imaging?
Answer:
Nuclear medicine includes anything that involves injecting radioactive emitters into the forgiving. You could break it up into two categories: remedial and diagnostic.
The therapeutic portion would include giving the patient radioactive emitters that are expected to kill something inside the lenient. For example, you could give the tolerant radioactive iodine if you need to verbs his thyroid gland because for cancer or hyperthyroidism.
The diagnostic part would include using radioactive emitters to photograph physiological functioning of the body. For example, you could give radiolabeled glucose (labeled beside a positron emitter) to a patient, afterwards use a PET scanner to see what parts of the body are most metabolically active. The utility within this is that cancers are usually the most metabolically live tissues in the body, so you can find tumor metastases this bearing.
So PET imaging is included under the umbrella-term of nuclear medication, although it is often run by the radiology race instead of the nuclear medicine family.
