In the present study, one PET maximum intensity projection image artifact was corrected by employing the method of retro-reconstruction.

FLAIR images had more image artifacts, but the image interpretation was not influenced.

Image artifacts were analyzed and compared using Wilcoxon paired signed rank-test.

Conclusion: Image artifacts are common and can lead to incorrect interpretations of OCT angiography images.

The qualitative evaluation was performed as a multireader analysis concerning lesion detection, lesion delineation and image artifacts.
