Quick question about my job experience-

I worked as a Radiology Medical Assistant at a local hospital, however due to space limitations in the field where you enter "experience name" I'm not sure if it would be okay for me to put down that I was a medical assistant.

Do you think it would be better (in the admissions committee's perspective) for me to write that I was a radiology assistant or a medical assistant? I don't have room for the entire title and know that this problem isn't that big of a deal/difference but I appreciate your advice!
