Chest Xray/Receiving Xray Report Question

So I had a chest X-ray on Sunday. They said they seen something super small, but it might be artifact. The doctor was not helpful (ER doctor) and basically rushed me out. I just wanted to know who would be calling me (the hospital or my family Dr), if I'd get a call regardless of the results, how soon I could expect a call, etc. He wouldn't even tell me if it was on my lungs or my heart... so you can imagine how stressed I am as a 20 year old.

Does anyone know how soon I could expect a call? Is it insane of me to want to call them and ask if they have the results? I had someone say I can call my family Dr and they might have the report.. is that true? Should I just call the hospital?

Thanks in advanced!
