Hi Nurseguy2005,
I graduated in 1990 with an AS in Rad Tech. I only practiced for ~5 years before I left the field to have my children. I decided not to return to RT and instead pursue a career in Nursing... I will graduate in May 2006
Rad Tech is a very interesting field. With your IT background, you would be a good candidate for PACS administration.
My personal reason for leaving Radiology was the limited patient contact. It was often like an assembly line. Also, there was zero patient teaching opportunities in Radiology, which is why I went into Nursing.
As far as job outlook, the RT field does occasionally get saturated. However, there are periods of high demand. Starting salaries are up there now and in some areas comparable to a starting salary for an RN.
It really depends on what you want to do... if you are looking for patient care and teaching, I would go for Nursing.
Good luck to you and feel free to PM me any specific questions.
