Patients with a case history of severe side-effects from iodine-containing contrast media present problems in later radiological examination. We report here on an alternative, the first extravascular use of Gd-DTPA in an X-ray urethrography.
By using the standard processing algorithm of our digital radiographic equipment and 60 ml undiluted Gd-DTPA meglumine (469 mg/ml) we achieved good contrast and could exclude the suspected urethral diverticulum in a 26-year-old man. No adverse reactions occurred.
Gd-DTPA seems to offer a reasonable contrast and may be used as an alternative extravascular contrast medium in selected conventional radiographic studies.
