She says she is not aware of any other lab investigating this imaging technique to detect liver trauma.
The talk "Detection of blunt force trauma liver injuries using shear wave elastography (3aBB1)" by Jiao Yu will be at 8 a.m. on Wednesday, November 17.

Dr. Yu has written a lay-language paper that describes this research in greater detail. It is available upon request and will be posted to ASA's virtual press room shortly before the meeting.
5) Mayan Pyramid Chirps like a Bird
Standing 79 feet tall, Chichen Itza's temple of Kukulkan is an impressive sight that has revealed much about the ancient Mayans to the keen eyes of archaeologists.
For acoustic scientists who study this temple and others like it, though, its looks are only half of the story. The sounds of the site, they believe, can enrich our understanding of the politics and culture of the people who once lived in this region.
"Once the Earth was a quieter place, and the ancients paid much more attention to what they heard in their environment," says David Lubman of DL Acoustics.
Lubman has studied the peculiar echoes that the temple at Chichen Itza produces. Visitors who clap hear the sound of their hands reflected back as an unrecognizable, high-pitched chirp -- a sound that some believe resembles the call of a bird.
To test this idea, Lubman recorded echoes from the temple and compared them to the noises made by the Quetzal, a bird native to this region that was an important part of Mayan culture. The temple was thought to be devoted to the god Quetzalcoatl, the "plumed serpent."
Sure enough, the spectrograms of both sounds bore a striking resemblance.
