Biomedical Engineering or Mechatronics

Hello,
I want to study Biomedical Engineering but I dont know where to study, can you guys help me?
I’m from Bolivia and got a 1770 on the SAT,
I don’t care neither the location nor the price of the university.

What do you think about studying both Mechatronics and Biomedical Engineering?

Can I get a B.Sc. in Mechatronics and then a Master in Biomedical Engineering?
Or would it be better a B.Sc. in BME and a master in BME?
I want to work with something to do with Prostheses and Tissue engineering

Starting with Mechanical Engineering and adding a Masters in BME is probably the best course of action for employment opportunities.

Better than starting with mechatronics and adding a Masters in BME?
