The Environmental Impact of Iodinated Contrast Media: Strategies for Optimized Use and Recycling.
J Comput Assist Tomogr
December 2024
Iodinated contrast media (ICM) is an integral and ubiquitous component of modern diagnostic imaging. Although most radiology practices are familiar with ICM administration and physiological excretion, they may be less aware of how much ICM is wasted on a per exam basis. Furthermore, radiologists may not recognize the environmental fate of discarded ICM waste.

- Patients with a history of severe reactions to iodinated contrast aren't rare in medical settings, especially during CT scans.
- Iodinated contrast is typically given intravenously, but it can also be used during urologic procedures, and past allergic reactions may still pose risks in these applications.
- The case presented shows that gadolinium-based contrast agents can be safely used as an alternative for assessing postoperative leaks in patients with severe iodinated contrast allergies.
Photon counting CT was recently introduced into clinical practice [Rajendran K, Petersilka M, Henning A, Shanblatt ER, Schmidt B, Flohr TG, Ferrero A, Baffour F, Diehn FE, Yu L, Rajiah P, Fletcher JG, Leng S, McCollough CH.

Optimization of dual-energy CT (DECT) workflow is critical for successful integration of DECT into practice. Patient selection strategies differ by scanner type and may be based on patient size, exam indication, or both. All stakeholders involved in patient scheduling and scan acquisition should be involved in patient triage to DECT.
