ARKA Clinical Decision Support is designed to meet all four criteria for Non-Device CDS under FD&C Act §520(o)(1)(E) and FDA's January 2026 final guidance on Clinical Decision Support Software. Recommendations support, not replace, the clinician's judgment. Every recommendation is anchored in a published guideline or peer-reviewed source, with the basis available for independent review. CLIN emphasizes imaging appropriateness at order entry.
This recommendation is intended to support, not replace, clinical judgment. It is generated by ARKA, software designed to meet the four criteria for Non-Device Clinical Decision Support under FD&C Act §520(o)(1)(E) and FDA's final guidance on Clinical Decision Support Software (January 2026). The clinician is responsible for the final decision.
AIIE Evidence
CT confirms first or atypical diverticulitis episodes; mild classic recurrences in confirmed disease may be managed without repeat imaging.
CT with IV contrast is appropriate to confirm a first episode of suspected acute diverticulitis and exclude complications. In patients with classic recurrent symptoms and prior imaging-confirmed disease, repeat imaging for every mild episode adds little.
