twinkling star signImaging A fanciful descriptor for the short linear radiations that extend from pulmonary vessels and parallel the long axis of the body on CT scans, most prominently seen at a 100-200HU window width; 'twinkling stars' help distinguish normal vessels from tumor masses, which may have the same CT density.
