Lesson 1Patient agreement and explanation: describing IV dye risks and benefits and breath-holding needsExplains how to get informed agreement for IV dye CT, clearly outlining benefits, possible risks, and options, while teaching workers to explain breath-holding steps, handle worry, and confirm patient understanding before scanning.
