[Abstract] Objective To study the clinical application value of magnetic resonance angiography (MRA) combined with CT angiography (CTA) in the diagnosis of cerebral vascular malformations (CVMs) in children.Materials and Methods A retrospectively analysis was conducted on the imaging data of 50 children with suspected CVMs who met the inclusion and exclusion criteria admitted to our hospital from January 2024 to December 2024. All children underwent digital subtraction angiography (DSA), CTA and MRA imaging examinations. The detection rates of CTA and MRA and their consistency with gold standard DSA were analyzed. The diagnostic efficacy of CTA, MRA and their combination in children with CVMs was analyzed.Results A total of 38 children with CVMs were detected by DSA. A total of 34 cases were detected by CTA, which was in good agreement with DSA (Kappa value was 0.606); and 33 cases were detected by MRA, and the consistency with DSA was moderate (Kappa value was 0.472); and 40 cases was detected by the combination of CTA and MRA, which was in good agreement with DSA (Kappa value was 0.767). The sensitivity and accuracy of CTA combined with MRA were higher than those of CTA or MRA alone (P < 0.05).Conclusions In the clinical diagnosis of CVMs in children, compared with the diagnoses of CTA or MRA alone, the diagnostic efficiency of MRA combined with CTA is superior.
