  schema:description "Being told not to eat for hours before a CT scan with contrast dye dates from older dyes that made people sick. Randomised trials, including one of more than 3,000 outpatients at a cancer centre, found no more sickness when people ate, and European radiologists recommend against fasting. Some hospitals still ask for it."@en ;
