Power Injectors - Video Lesson

Hey everybody, welcome to today's lesson on patient care in MRI. This lesson focuses on how power injectors, fluoro triggering, timing bolus methods, and automatic bolus tracking work together to optimize contrast enhancement and image timing. Let's get started. Contrast enhanced imaging studies rely on precise coordination between contrast delivery and image acquisition. The timing and method of contrast injection can make the difference between diagnostic quality images and non diagnostically viable results. First, let's discuss what a power injector is. A power injector is an electromechanical device designed to deliver contrast media into a patient's vascular system at a controlled rate and pressure. In MRI, power injectors are typically nonferromagnetic and MR conditional, using pneumatic or hydraulic drive systems to ensure safety within the magnetic
