Abstract
Biodegradable computed tomography (CT) contrast agents comprising a polyiodinated aryl contrast agent that is crosslinked by an organic disulfide are described herein. The contrast agents can be used to image a tissue region by administering an effective amount of the biodegradable CT contrast agent to a subject, allowing a sufficient amount of time for the biodegradable CT contrast agent to enter the tissue region, and performing x-ray computed tomography imaging of the tissue region of the subject.
