[Clinical comparative study between the contrast media Biligram, Endomirabil and Biliscopin (author's transl)].

The contrast media Biligram, Endomirabil und Biliscopin are tested in comparative series in a total of 304 patients. The optimal time of exposure for visulaization of the bile ducts and gallbladder is between 60 and 90 minutes in combined filling with Biloptin and the contrast medium used. The contrast media do not differ from one another in a significant manner in respect of contrast densification. All three constrast media have low side effects for injection times of 5 minutes. The side effect quota increases with the amount of injected contrast medium. Of all three contrast media, Biliscopin has the lowest side effect quota.
