Summary

Gallbladder visualization after ioxaglate angiography suggests the hepatobiliary system aids in contrast excretion. This finding is notable in patients without kidney issues, highlighting an alternative excretion pathway for ioxaglate.

Area of Science:

  • Radiology
  • Medical Imaging
  • Contrast Media

Background:

  • Ioxaglate is an iodinated contrast agent used in angiography.
  • Renal excretion is the primary pathway for most iodinated contrast agents.

Purpose of the Study:

  • To investigate the role of the hepatobiliary tract in the excretion of ioxaglate.
  • To determine if gallbladder opacification occurs after abdominal angiography with ioxaglate.

Main Methods:

  • CT examination of 35 patients 15-30 minutes post-abdominal angiography.
  • Administration of ioxaglate contrast agent.
  • Assessment of gallbladder visualization on CT scans.

Main Results:

  • Gallbladder opacification was observed in 12 out of 35 patients.

  • Visualization occurred in the absence of clinical evidence of renal impairment.

    • Conclusions:

    • The hepatobiliary tract plays a role in the excretion of ioxaglate.
    • Gallbladder opacification on CT scans shortly after angiography indicates hepatobiliary excretion of ioxaglate.
