MEDFORD - A family of an elderly war veteran is suing a Suffolk County radiology center after they say an accident there led to a stroke that killed him.

Dan Mahony, 79, was at Zwanger-Pesiri Radiology in Medford in 2009 to get an MRI. His son says his father was told to remove all metal from his body before the MRI, but he was never told anything about leaving behind the metal walker he used. Upon entering the room, the magnetic field was so strong his son says the walker was yanked out from under Mahony and he fell and hit his head on the floor.

Mahony suffered a stroke two days after the accident and died two months after that.

The attorney representing Zwanger-Pesiri Radiology refused to comment at this time. The case is going to court tomorrow in Riverhead.
