Here is an article on the CT scanning of some of the British Museums mummies which have remained wrapped over the last couple centuries. The mummies include a Third intermediate period priestess and temple singer named Tamut who died at Thebes around 900 BC.
An unknown man was revealed during the scans in the coffin of a woman. The man had bad teeth and probably suffered terribly, amazing technology!
The mummies will be presented among others in Ancient Lives from May 22 -November 30, 2014 at the British Museum
