Radiomic Modeling in Differentiating Uncomplicated From Complicated Acute Appendicitis

May 4, 2023 updated by: Kecheng Zhang

Development and Validation of an Individualized Nomogram to Differentiate Uncomplicated From Complicated Acute Appendicitis in Adults: a Multicenter Study

Non-operative management (NOM) with antibiotics may be a safe alternative to surgery for uncomplicated appendicitis, but preoperative differentiation between uncomplicated and complicated appendicitis is challenging. The study aimed to develop a clinical-radiomics nomogram to distinguish uncomplicated from complicated appendicitis.
