Image: Coronary CT angiography images demonstrate examples of high-risk plaque features. A, Image was obtained in a 63-year-old man with partially calcified plaque, positive remodeling (vertical arrow), and spotty calcium (horizontal arrow). B, A cross-sectional view of a noncalcified plaque in a 65-year-old man demonstrates a napkin-ring sign with a central low-attenuation area, surrounded by a peripheral rim of higher attenuation (arrow) next to the lumen (∗). C, Image in a 60-year-old woman with partially calcified plaque demonstrates a low CT number in the midportion (arrow) (Photo courtesy of the journal Radiology).

Image: Photoacoustic/ultrasound images taken with the new system show a human finger joint from different angles. The images on the right (b and d) show anatomic structures revealed by the ultrasound. The images on the left (a and c) show the photoacoustics data overlaying the ultrasound data. The bright yellow and red at the top of the finger show the skin and blood vessels running parallel to the finger (Photo courtesy of Pim van den Berg/Khalid Daoudi).
