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

Abstract

 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.
