I've just been watching a video of a 757 suffering a bird strike on take off. The pilots continue with their take off, declare a MAYDAY, shut the engine down and proceed to land without any issues.

Are these engine reused after an event like this? Are they sent away to Rolls Royce, Pratt & Whitney etc to be repaired? Or are they always deemed a complete write off and replaced with new?
Obviously turbine engines are highly balanced complex pieces of machinery so I can imagine once FOD has damaged this balancing the damage is pretty high.
