Imaging plays a pivotal role in confirming or excluding the diagnosis and identifying complications that influence management pathways. This narrative review synthesizes contemporary evidence and consensusbased imaging protocols for appendicitis, with a focus on computed tomography, magnetic resonance imaging, and ultrasound. The article explores advanced diagnostic criteria, interpretation challenges, imaging algorithms derived from professional society guidelines, and special considerations including pregnancy and pediatric populations. Clinical practice recommendations by the World Society of Emergency Surgery, European Association of Endoscopic Surgery, American College of Radiology, and Infectious Diseases Society of America are incorporated to frame best practices.  \nKey Words: Magnetic resonance imaging; Computed tomography; Ultrasound; Appendicitis; Management; Pregnancy; Children  \n©The Author(s) 2025.

Imaging of appendicitis  \nCore Tip: Imaging is essential in the accurate diagnosis and management of acute ap-pendicitis, with computed tomography as the gold standard in adults, ultrasound preferred in children and pregnant patients, and magnetic resonance imaging increa-singly used to reduce radiation exposure. This article integrates evidence-based imaging protocols and professional society guidelines to guide optimal imaging strategies across various clinical scenarios.  \nCitation: Perera Molligoda Arachchige AS, Teixeira de Castro Gonçalves Ortega AC, Amorim Moreira Alves G.
