NSF vs CIN - CIN or NSF - NSF or CIN App

NSF (Nephrogenic Systemic Fibrosis) vs. CIN (Contrast-induced Nephropathy): weighing risks and benefits - Contrast Media - Contrast Agents - Gadolinium - Iodine - Iodinated Contrast - Update

New app NSF vs. CIN: weighing risks and benefits. It´s 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. This app provides a simple and practical approach to minimize the risk of developing NSF and CIN.

Your comments and suggestions are very welcome. We hope you enjoy and feel free to share this app.

Can this app be used in the USA ? Yes.

Appendix A Examples of mobile apps that are NOT medical devices
This Appendix provides a representative list of mobile app functionalities to illustrate the types of mobile apps that could be used in a healthcare environment, in clinical care or patient management, but are not considered medical devices. Because these mobile apps are not considered medical devices, FDA does not regulate them.
2. Mobile apps that are intended for health care providers to use as educational tools for medical training or to reinforce training previously received. These may have more functionality than providing an electronic copy of text (e.g., videos, interactive diagrams), but are not devices because they are intended generally for user education and are not intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease by facilitating a health professional’s assessment of a specific patient, replacing the judgment of clinical personnel, or performing any clinical assessment.
