This week, we’re shining a bright (and perfectly calibrated πŸ˜‰) spotlight on one of the quiet heroes of patient care, our CT Technologist, Abby T.
Radiologic Technologists are often behind the scenes but their work is truly at the heart of diagnosis.

They help us see what can’t be seen and help guide treatment that supports patient care every day.
We appreciate the steady support and teamwork Abby provides in CT and the role she plays in our daily patient workflow.πŸ’•
Thank you, Abby, and Happy Rad Tech Week to all who support diagnostic imaging.
