Radiology Support, Communication and Alignment Network

The R-SCAN project was funded by a Center for Medicare and Medicaid Services’ Transforming Clinical Practice Initiative grant conducted from 2015 through 2019 to enable radiologists and referring clinicians to collaborate on improving the appropriateness of imaging exams ordered.

Over 100 practices participated in an R-SCAN project by implementing a Plan-Do-Study-Act (PDSA) cycle to improve imaging care for some of the most frequently ordered exams to include imaging for low back pain, suspected pulmonary embolism, and minor head trauma.

R-SCAN in Practice


Ten case studies highlighting the work of R-SCAN teams pursuing various projects are available that feature the successes achieved by practices resulting in improved imaging care.

Clinical Decision Support Registry Concept Feasibility


The R-SCAN project also served to test the feasibility of using electronical available clinical decision support data to help facility personnel identify areas of potential imaging overuse and guide collaborations to improve imaging appropriateness. This work led to the creation of the Clinical Decision Support Registry (CDSR) Committee and a CDSR workgroup with members now working on the registry’s development phase.

See how one practice used interactive electronic R-SCAN reports to improve the ordering of exams for suspected pulmonary embolism.
