QA Main || QA 0 || QA 1 || QA 2 || QA 3 || QA 4

The Iowa MH-CRC neuroimaging lab rates the relative level of motion artifact and quality of image sets.

The QA rating is on a 5 point scale running from 0 to 4:

• A rating of 0 represents extreme motion artifact with horrible image quality.
• A rating of 1 represents severe motion artifact with poor image quality.
• A rating of 2 represents moderate motion artifact with intermediate image quality.
• A rating of 3 represents limited motion artifact with good image quality
• A rating of 4 represents no motion artifact with excellent image quality.

The following links contain gold standard QA ratings for each of the levels on the scale:
