Should medical imaging prioritize lower radiation exposure even if the procedure costs more?
In 2026, the Mayo Clinic Arizona implemented an ultra-low-dose CT protocol for renal stone surveillance. This shift successfully reduced the mean radiation dose for patients by 66%.
Why it matters
Researchers identified radiation concerns and limited awareness among staff as primary drivers for the historical overuse of conventional imaging methods. By transitioning to this protocol, the clinic aimed to improve clinical accuracy while simultaneously addressing significant radiation safety risks.
The new protocol achieved a mean radiation dose of 1.7 mSv, significantly lowering exposure compared to traditional methods. While Medicare fees for the new CT protocol are $180.82 compared to the $133.59 fee for prior combined imaging, usage of ultrasound dropped by 71.4%.
The players
Mayo Clinic Arizona
This major medical facility in Phoenix provides comprehensive healthcare services and conducts clinical research.
Journal of the American College of Radiology
This peer-reviewed publication focuses on diagnostic imaging, interventional radiology, and radiation oncology research.
The details
A multidisciplinary team utilized the Six Sigma framework to analyze baseline imaging patterns and incorporate tin-filter technology. This approach allowed the institution to successfully transition from ultrasound and radiography to more precise ultra-low-dose CT surveillance.
Timeline

The Big Picture
The adoption of the Six Sigma quality management framework reflects a growing trend in healthcare to apply industrial efficiency models to clinical settings. This project follows the established pattern of reducing diagnostic variability and resource waste in hospital environments.
Patients undergoing renal stone surveillance at the clinic can now expect significantly lower radiation exposure compared to previous imaging standards. While the new diagnostic procedure carries a higher Medicare fee, it offers improved monitoring precision for those managed at this facility.
The takeaway
Healthcare institutions can significantly enhance patient safety by systematically auditing diagnostic imaging utilization. Adopting standardized protocols like ultra-low-dose CT helps facilities balance clinical efficacy with necessary radiation reduction.
