Visitors can also cut through the coffins and mummy in cross-section
Neswaiu lived in the third century BC at the temple of the god Montu in Thebes - modern-day Luxor. His remains were gifted to the Medelhavsmuseet in 1928 when it first opened.
"We know that his mother's name was Takerheb and we also know that he belonged to the upper classes of Egyptian society because he could afford an expensive mummification. Not everybody could," said Sofia Häggman.
"He also has a gilded cartonnage, he has two coffins and he has a lot of amulets on his mummy, small pieces of jewellery that would aid him into eternal life."
Researchers have tried to see what was inside his mummy before. His stomach was opened in 1962 and a tissue sample removed and X-rays have also been taken previously. But the digital autopsy has added much more detail to their understanding.
"He was healthy, pretty muscular apparently. He lived until he was 50 or 60 years old which was comparatively old in ancient Egypt and he might have died from an infection in one of his teeth which affected the bone and could have caused blood poisoning," said Ms Häggman.
The scanning process has also given them further insight into the mummification process.
"You can see the cut where the internal organs were taken out. You can see the wrapped packages of intestines, of the lungs and the liver they put back inside the body and you can see how the cut was then resealed and they put an amulet in the shape of the embalmer's two fingers across the cut to protect it."
Scanning also pinpointed in three dimensions where 120 amulets found on his body were placed, including a falcon-shaped one. The data was used to 3D print a mould and then cast an exact replica of the falcon while leaving the original undisturbed on the mummy.
What Neswaiu doesn't have any more is a brain - that was not preserved. Humans, the Egyptians believed, thought with their hearts.
