Magnetic Resonance Urography in Diagnosing Congenital Renal Dysplasia in Children / 实用放射学杂志

ABSTRACT

Objective To approach the value of MR urography (MRU) in diagnosis of congenital renal dysplasia in children.Methods 13 children with congenital renal dysplasia and renal inadequacy were examined by routine MRI and MRU with heavy T_2 weighted single stimulation fast spin echo sequences.Results The congenital atopic dysplastic rens located at pelvis in one case and at below nephritic pit in one case were not detected by MR imaging and original MRU images,respectively.Multicystic dysplastic kidney could be well showed by MRU MIP images, but the cases with clubbed renal pelvis were not well demonstrated by MRU. All cases and the complications were correctly diagnosed by routine MRI, original MRU and MRU MIP images.Conclusion MR urography in combination with routine MRI is of important value in diagnosing congenital renal dysplasia in children.
