I think it would depend on what you are "really" interested in. If nuc-med, ultra sound or X-ray is what your interested and you don't want to provide "patient care" then go that way.
If you think you might like to try a little of everything, make decent money, go the RN way, and I would go ahead and get your BSN, it can and will open even more doors for you. Nursing for the most part is about patient care, ie taking care of the patient. However there are areas of nursing that have limited patient care such as OR nursing, or management, patient advocate or teaching. There are also areas that allow more autonomy such as home health nurses.
By getting your BSN, you open the door to a natural progression of more education and a bigger pay check. I went nurse anesthetist and don't regret it for a moment, and the pay isn't that bad either ie almost 6 figures with 7 weeks of vacation a year.
