  • Title: [Selective renal angiography with fractionated contrast medium injection. An experimental study in the dog (author's transl)].
    Author: Burgener FA, Fischer HW.
    Journal: Rofo; 1975 Oct; 123(4):334-7. PubMed ID: 129392.
    Abstract:
    Fractionated contrast medium was compared with the conventional technique in 96 selective renal angiograms in the dog. The only possible clinical significance might be that improved visualisation of the renal vein was obtained with this technique without increasing the total administered dose. The overall best result in this regard was obtained with 2 and 6 ml. diatrizoate 60% injected with an interval of five seconds. Compared with other vasodilators, contrast material reflux into the aorta was not reduced and the vasodilator effect on the main renal, segmental and interlobar arteries was not constant and less marked.
