### 1/5 — Not what clinicians need

*2025-08-07*

We need the appropriateness criteria. Help choosing the right test. This stuff here is trivial and not what clinicians generally need.

### 2/5 — Could be so much more

*2023-11-19*

This would be a really useful app if it included the appropriateness criteria. As it stands, I would not recommend the app.

### 1/5 — Nothing in this app (almost)

*2021-10-25*

I am writing this review on Oct 24, 2021.  From what I can tell, this app has been released in the App Store for at least 1 year.  

When you open the app, there are 3 icons you can click: “Contrast Reaction”, “Reporting and Data Systems (RADS)”, and “Incidental Findings”. I was most interested in the Incidental Findings section.

Clicking on either the first or third links displays a page which reads “Coming Soon!” Clicking on the second link displays a page which shows “O-RADS for US”.  This is literally the only functional bit of this app.

I don’t understand why this was released if none of the links are active. The fact that the ACR decided to release it and hasn’t updated it to flesh it out more is hilariously a commentary on the state of the field of radiology in medicine in America today, to be honest.  Lol.

### 5/5 — Looking forward to see more info soon.

*2021-08-19*

This app is good and has potential to be a great tool for every radiologist out there. We just need more informations. Thanks.
