Vesico-ureteric
reflux is a congenital disorder of the paediatric renal tract, for which the
current gold standard is the Micturating Cystourethrogram (MCUG). This study
evaluated the feasibility of MR voiding cystourethrography using dilute
intravesical gadolinium in unsedated infants. Real time interactive switching
between gradient echo (SPGR) and SSFSE based pulse sequences allowed 6
children with urinary tract abnormalities to undergo both MCUG and MRI. There
was 83% concordance between MCUG and MRVC regarding vesicoureteric reflux,
and complete agreement regarding the urethra and bladder. Fluoroscopic MR assessment
of the complete paediatric renal tract is possible in unsedated infants.
