Advantages and disadvantages of nuclear medication?

Advantages: nuclear medicine is--can be-- physiologic. The uptake and ending of the radiotracer is dependent on the function of the organ. That means it can relate you how well the organ is working, instead of showing pretty pictures of it. For example, nuclear studies quantify renal function and make clear to us how well the thyroid gland take up iodine.

In gallbladder studies, the radiotracer is excreted by the liver , taken up by the gallbladder and excreted into the bowel. If the gallbladder does not take up the tracer, or the tracer is not excreted into the bowel, in attendance is blockage. An ultrasound shows us whether there are gallstones , and whether at hand is inflammation around the gallbladder , but it does not show functional obstruction. (If we see a stone contained by the bile duct, we infer blockage, but it is difficult to see the entire bile duct on ultrasound .)

Radiotracer is taken up by living cells, so a heart study shows what cut of the heart muscle is alive vs. dead after a heart attack . (Both nuclear med and cardiac reverberate can show how hard the heart is pumping.)

In the brain , nuclear drug is helpful contained by showing which areas are metabolically active. This have been immensely useful and interesting surrounded by research, it's a way of localizing what parts of the brain are busy during different sorts of activities or even thought processes.

PET (positron seepage tomography), a branch of nuclear medicine, is severely useful surrounded by the work up of cancer . A nodule on CT scan may or may not be cancer , but the PET tells us if it is severely active metabolically, as cancer usually is.

Disadvantages: the most important disadvantage is anatomic resolution. Nuc med images aren't "pretty," they do not show much anatomic detail. For this use, we have started to combine modalities--it is presently possible to get a PET-CT which provides both anatomic and physiologic information .

Another disadvantage is the exposure to radiation. A typical nuc med exam exposes a tolerant to a little more radiation than a chest x-ray-- but smaller amount than a CT scan.

People should never treat radiation exposure cavalierly, but if the study is needed for diagnosis , the benefit outweighs the risk of not having it.
locates things contained by body finds problem

disadvantages lots of radiation exposure

advantage you dont own to do get exposed every daytime!

Ps I wouldnt be a nuclear med tech though
