CT Colonography Registry

The CTC Registry provides evidence-based health outcomes and process data for decision-making purposes. The registry allows facilities to compare results to regional and national benchmarks for quality improvement and is one of eight registries that comprise the National Radiology Data Registry (NRDR).

The CTC Registry measures include the following:

Process measures:

  • Rate of adequacy of diagnostic CTC examination
  • Rate of adequacy of screening CTC examination

Outcome measures:

  • Rate of colonic perforation
  • True positive rate
  • Extracolonic findings

Participating facilities and physicians receive quarterly reports based on aggregated benchmarks to facilitate patient safety and quality improvement efforts. Participation also allows credit for Maintenance of Certification (MOC) Part IV requirements of the American Board of Radiology (ABR).
