How do imaging leaders determine the right contrast delivery workflow for their department? 

Imaging leaders are constantly looking for ways to improve efficiency, support staff, and deliver a better patient experience. But when it comes to contrast delivery, there is rarely a one-size-fits-all solution. 

In this episode of Medical Imaging Matters, AHRA Executive Director Jason Newmark continues the conversation on contrast delivery with Michael Schlenk, MRI manager at Naples Comprehensive Health, and David Kos, medical imaging manager at Hoag Memorial Hospital. 

Drawing from their own experiences across MRI, CT, emergency, inpatient, and outpatient environments, Michael and David explain why successful workflows depend on much more than technology alone. Staffing models, patient populations, clinical priorities, available resources, and even regional differences can all influence what works best for a department. 

Perhaps the biggest takeaway is that workflow improvement doesn't always require a major investment or a complete overhaul. Sometimes it starts with asking a simple question: Why are we doing it this way? 

Michael and David share how regularly revisiting long-standing processes, listening to frontline staff, and staying open to new approaches can create a better experience for both patients and teams.
