are radiology, CT, MRI, Ultra sound, or nuclear radiation tech's ranked as officers in the military ?  ?

No, you loser. F*ck you. 

Nope

Techs dont require Bachelors Degrees so can not be commissioned. 

Nope.  Techs are enlisted.  

It depends. Ultra sound, no for sure.  Radiology - a mix I think. 

Basically, doctors, and nurses (who are RN's) are officers, and Med-Aids are not.  The civilian world does not really have an equivalent to Med-Aids. 

Oh; Med-Aids are what the Canadian Forces calls them.  Many lab tech type jobs are done by Med-Aids.

nope, its an enlisted job

not freakin' likely ... the MD in charge of the Imaging Department at a military hospital is an officer, not the techs

Does not matter what you are it's your level of education if you hold a professional degree and attend a military academy you can be an officer.
