Plastic waste declined by 55% in weight and 62% in volume,

yielding a 30-ton annual drop in CO²-equivalent emissions including the whole cycle of life of the iodine contrast consumable.

Radiology staff reported high satisfaction and improved work environments. Financially, the hospital saved €154,820 annually due to reduced agent and consumable waste. The global approach on the ecological impact of CT injections was really appreciated by the radiology staff who now see things much greener.
