Evaluation of differential renal function in children – a comparative study between magnetic resonance urography and dynamic renal scintigraphy

Urinary system anomalies, both congenital and acquired, constitute a relatively common clinical problem in children. The main role of diagnostic imaging is to determine early diagnosis and support therapeutic decisions to prevent the development of chronic renal disease. The aim of this study was to evaluate the utility of magnetic resonance urography (MRU) in assessment of urinary system in children, by comparing differential renal function calculated using MRU with dynamic renal scintigraphy (DRS). The study group consisted of 46 patients aged 1 week to 17 years (median 7 (0.5; 13) years, 17 (37
