ACR Appropriateness Criteria® Suspected and Known Renal or Splanchnic Artery Aneurysm

The authors aim to provide evidence-based recommendations for the imaging evaluation of suspected and known renal and splanchnic artery aneurysms across various clinical scenarios, including initial evaluation and surveillance in both adults and pregnant patients. They review the roles of different imaging modalities, such as CTA, MRA, and ultrasound, emphasizing their diagnostic performance and safety considerations to optimize imaging utilization and enhance patient-centered management. The guidelines are grounded in systematic literature analysis and expert consensus, ensuring they reflect current best practices in vascular imaging.
