MULTICYSTIC DYSPLASTIC KIDNEY - ANOTHER APPLICATION OF TC-99M MAG3

The value of (99m)Technetium-mercapto acetyl triglycine (Tc-99m MAG3) in the investigation of 10 children with suspected multicystic dysplas tic kidney (MCDK) has been assessed. The condition has to be distingui shed from hydronephrosis, usually caused by pelviureteric junction obs truction. Based on our findings, we propose that Tc-99m MAG3 replace T c-99m DMSA because it allows a better assessment of the contralateral kidney and permits a full assessment where the diagnosis is hydronephr osis rather than MCDK.
