Contrast Media: NSF vs. CIN

By Sandro Fenelon

This app is only available on the App Store for iOS devices.


Contrast Media is a user-friendly app designed by academic radiologists to help you choose the safest contrast agent (iodine or gadolinium) when imaging patients with renal impairment. It is an easy and convenient way to help healthcare professionals in their daily practices, including nurses, physician assistants, radiology technologists, radiographers, medical students, interns, residents, clinicians, surgeons, oncologists, nephrologists, urologists, gastroenterologists, radiologists and other medical specialists.

Choosing the right agent for the right patient remains a challenge, and one should always weigh the risks and benefits of each option. This app provides a simple and practical approach to minimize the risk of developing NSF and CIN.

Article published on Pubmed
"This app aggregates multiple eGFR calculators into a single app and integrates text-based contrast imaging decision support. Data for both CIN and NSF for respective contrast media subclasses are conveniently centralized and summarized, with tailored presentation of evidence-based risk estimates and suggested protocol guidance for a given eGFR”.
