Our experience confirms that multipatient injection is an effective, replicable strategy to lower contrast media waste, lessen environmental impact, boost operational efficiency, and yield significant cost savings. This model may be adopted by other healthcare facilities seeking greener, more sustainable imaging practices. By integrating multipatient mode into routine CT workflows, institutions can advance sustainable imaging goals, and generate broader awareness about eco-friendly healthcare solutions. Future research should carefully examine expansions of this practice to other imaging modalities and other type of contrast media. The results may differ on smaller hospitals or CT scan with less daily number of patient but the multi patient mode will always be greener than the single use mode. It is now essential to have a comprehensive reflection on the ecological impact of radiology and to rethink practices, starting with the simplest actions, such as comparing plastic consumables or recycling contrast products.
