|
Appropriateness Category Name |
Appropriateness Rating |
Appropriateness Category Definition |
|
Usually Appropriate |
7, 8, or 9 |
The imaging procedure or treatment is indicated in the specified clinical scenarios at a favorable risk-benefit ratio for patients. |
|
May Be Appropriate |
4, 5, or 6 |
The imaging procedure or treatment may be indicated in the specified clinical scenarios as an alternative to imaging procedures or treatments with a more favorable risk-benefit ratio, or the risk-benefit ratio for patients is equivocal. |
|
May Be Appropriate (Disagreement) |
5 |
The individual ratings are too dispersed from the panel median. The different label provides transparency regarding the panel’s recommendation. “May be appropriate” is the rating category and a rating of 5 is assigned. |
|
Usually Not Appropriate |
1, 2, or 3 |
The imaging procedure or treatment is unlikely to be indicated in the specified clinical scenarios, or the risk-benefit ratio for patients is likely to be unfavorable. |
