Its been interesting to know a lot of people have been making presumptions and also giving half baked knowledge about nukes.
As seen over the years nukes never had high demand as the types of studies done are limited and are for specific purposes. Most of the studies done in small private hospitals are typically read by radiologists ... like bones and renal.
As its known the demand of a nuclear medicine physician is more in academic institutions. This does not mean that there ARE NO PRIVATE PRACTICING NUKES. There are jobs available in both the places and the money is comparable or more than specialities like medicine and peds. Some of the Nukes guys earn equal or more than the rads ... although these are a select few who are doing really well.
Nukes has recently gained popularity in PET/CT, SPECT/CT, for oncology.
New radiotracers are in development, and will reach the market soon for specific tumours like prostate cancer, carcinoid tumors( in oncology), for Alzhimeirs, Parkinsons(in neurology) and also for cardiac imaging. Knowledge base for the average rad will be limited in the comming years as this field expands and also because the training for rads resident in nukes will be less.
Presently Nukes residency is undergoign a change. Plans are to extend it to 3 years from 2 years. This to give nuks residents training in CT.
This will help interpretation of both SPECT and PET CTs.
Regarding RIT(radioimmunotherapy), I believe it will remain in the hands of nukes, as for one you need a license to dispense these radioactive drugs and these therapy are a little more complicated that your average chemo. Complicated dose calcuations are required for administration of RIT. Also newer RITs are on the horizon.
Heard about radiovirotherapy? ;-) the next big thing
Things may change who know? No one wanted to go into rads 10 years ago .... graduating residents had to go into fellowships as they could not find jobs; same with anesthesia. Things may change.
Overall the job market is tight, but if you are competitive enough there are opportunities out there if you are interested in Nukes.
BTW Some one wanted to know about Molecular Imaging
" Molecular imagingoften called the next frontier in diagnostic imaging because it combines cutting-edge imaging technology with the power of molecular biologyis poised to dominate all imaging modalities and influence the daily practice of medicine. This field relies on the complementary skills of scientists and professionals, including nuclear medicine physicians, radiologists, biologists, chemists, engineers and physicists, and its this interrelationship that allows for the continuation of rapid advances and integration across medical specialties."
"Molecular imaging will eventually lead to determining the pathophysiology of disease processes at the cellular or molecular level."
