- the choice of the preferred method depends in part on according to the diagnostic question, but is also determined by the available device options for the doctor.

- the choice of a suitable contrast medium also varies depending on the particular question.
- the suitability of the contrast medium for a specific task is determined not least by its (enrichment) distribution behavior in the organism.
- contrast agents based on triiodobenzene have been able to prevail, since these compounds have a high X-ray density and have a low general and local toxicity and are very soluble in water.

- the hydrogenation is complete after 5 hours and the catalyst is filtered off. The filtrate is evaporated to dryness and used in the next step without further purification.
- the remaining residue is taken up in 300 ml of water and adjusted to pH 2.0 with a cation exchanger (H + form).
- the filtrate obtained after suction extraction from the ion exchanger supplies the pentacarboxylic acid as a colorless powder after freeze-drying.
