Abstract

BACKGROUND:Adnexal torsion (AT), a serious gynaecological emergency, often presents with non‐specific symptoms leading to delayed diagnosis. OBJECTIVE: To compare the test accuracy of ultrasound, computed tomography (CT) and magnetic resonance imaging (MRI) to diagnose AT. SEARCH STRATEGY: We searched EMBASE, MEDLINE and Cochrane CENTRAL until December 2019. SELECTION CRITERIA: Studies reporting on the accuracy of any imaging modality (Index Test) in female patients (paediatric and adult) suspected of AT compared with surgical diagnosis and/or standard clinical/radiological follow‐up period until resolution of symptoms (Reference Standard). DATA COLLECTION AND ANALYSIS: We assessed study quality using QUADAS‐2. We conducted test accuracy meta‐analysis using a univariate model or a hierarchical model.
