The Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect may spin up or spin down 5-km-radius asteroids on a 10 8 -year timescale. Smaller asteroids spin up or down even faster due to the radius-squared dependence of the YORP timescale. The mechanism is the absorption of sunlight and its re-emission

## Abstract A liver‐metastasis model was used to study the ability of fast spin‐echo (FSE) imaging to show small lesions (1 pixel in diameter) relative to conventional spin‐echo imaging. FSE images of the liver‐metastasis phantom were acquired with various phase‐encode reordering schemes to manipul
