title: [New contrast agents of the ionic group (Rayvist 300 and Rayvist 350)].
abstract: Using the newest ionic contrast agents Rayvist 300 and Rayvist 350, investigations were made which factors contribute to the quality of an urogram. The parameters (ml contrast medium/kg, mg iodine/sq. meter, mg iodine/kg, ml contrast medium/m2) were calculated. The results showed that high doses of the contrast agent do not guarantee good quality of urograms. A higher concentrated contrast agent (in this series Rayvist 350) gave better urograms and contrast respectively. High iodine dosage, associated with low concentration did produce worse results. Dose recommendations are given for children.
