CRJ200 flight crew reported hearing a thud passing 13;000 ft. As the aircraft rolled slightly to the left the captain corrected with aileron. An emergency is declared and the flight returns to the departure airport; where post flight inspection reveals a large section of the thrust reverser has been ripped off

Narrative:
On climb out at approx 13;000 feet and 310 knots heard a thud and the aircraft rolled slightly left. Captain disconnected autopilot and stated we had a control issue and we should declare an emergency. We were approx 50 miles north of [our departure] and so elected to declare an emergency and return. I checked hydraulics; flight control indications and pressurization and everything appeared normal except for a slight amount of left aileron trim being required for level flight. The handling issue got significantly better as we slowed so we suspected structural damage. As we returned we discussed possible scenarios involving aircraft handling deteriorating as we slowed for landing and how we may handle it. We were initially assigned [the left runway] but requested [the right] due to its longer length. I briefed the flight attendant as per [company sops] and informed her to expect a normal landing. As we slowed to 200 knots handling returned to normal and we landed normally. Upon post flight inspection; there was a large section of the thrust reverser that had been ripped off.
