THE DIAGNOSTIC VALUE OF MAGNETIC RESONANCE (MR) UROGRAPHY IN CHILDREN: SINGLE CENTER EXPERIENCE
Purpose or Case Report: To illustrate the diagnostic value of magnetic resonance (MR) urography in children with urinary tract abnormalities.
Methods & Materials: Eight children who had MR urography comprises of conventional and heavily T2 weighted sequences with or without post-gadolinium were reviewed. Main indications for MR urography study in these patients were delineation of the suspected anatomical urinary tract anomalies which included duplex kidneys, ectopic ureter and pelviureteric obstruction among others. Results were correlated with other imaging modalities ie ultrasound, micturating cystourethrography and /or Tc99m-DTPA scintigraphy. Intraoperative findings were also reviewed to see descriptive correlation with the pre-operative MR urography findings. The technique of MR urography will also be detailed out.
Results: MR urography provided excellent anatomical delineation of the urinary tract anomalies especially in dilated urinary tracts and mapping the exact ureteric insertion either normal or ectopic. The majority of our cases were duplicated systems and few of these cases correlated well with intraoperative findings.

Conclusions: MR urography can be a great anatomical assessment tool with regards to urinary tract abnormalities.
