Diagnostic Efficacy and Imaging Characteristics of MRI Combined with CT in Children with Duplex Kidney

Introduction. To analyze the diagnostic efficacy and imaging characteristics of MRI combined with CT in children with duplication of kidney. Methods. A retrospective analysis was conducted of the clinical data of 40 children with duplication of kidney admitted to our hospital between January 2019 and January 2024 and confirmed surgically. All patients underwent MRI and CT examinations, with surgery as the gold standard. The diagnostic efficacy of MRI and CT in children with duplication of kidney was analyzed. Results. CT confirmed 32 cases of duplication of kidney, with a diagnostic rate of 80%. MRI confirmed 33 cases of duplication of kidney, with a diagnostic rate of 82.50%. CT combined with MRI confirmed 39 cases of duplication of kidney, with a diagnostic rate of 97.50%. The diagnostic rate of CT combined with MRI for duplication of kidney was higher than that of CT or MRI alone (P < .05). The diagnostic accuracy of CT combined with MRI for hydronephrosis duplication was 100%, significantly higher than the 77.27 and 81.82% rates of CT and MRI alone (P < .05) . There was no significant difference in the diagnostic accuracy of CT or MRI alone for developmental and dysplastic duplication (P > .05). Conclusions. MRI combined with CT has a high diagnostic efficacy for duplex kidney and its classification in children, which can provide a reference for clinical diagnosis and treatment and can be vigorously promoted in clinical practice.
