Totally depends. Mostly on where you are in Germany, and to a degree whether you're willing to call a few different doctors. An acquaintance with a shoulder injury got an appointment with an orthopedic specialist within a week, who recommended an MRI. The second hospital she called just happened to have a free MRI slot the next morning.
Personally, I never had to have an MRI, but when I needed to see a specialist for acute back pain, I got an appointment (and a fix) within 24h. I have never in my life waited months for an appointment with any specialist.
This is all on public health insurance (and without any additional charge, ie. the MRI was "free"). Relatives tell me it's much more difficult in other places in Germany; I sometimes wonder if they should just get an appointment here, Germany isn't that big.
