Adoption of a diagnostic certainty scale in abdominal imaging: 2-year experience at an academic institution.

DCPs are very common in abdominal imaging reports and can be further clarified with CS use. Although voluntary CS adoption increased 13-fold over 2 years, > 50% of reports with DCPs lacked the CS at study's end. More stringent interventions, including embedding the scale in report templates, are likely needed to reduce inter-radiologist variation and decrease ambiguity in conveying diagnostic certainty to referring providers and patients.
