A score of 5 (“excellent”) indicates diagnostic quality without any artifacts; score of 4 (“Good”) indicates diagnostic quality with minor artifacts; score of 3 (“Fair”) indicates diagnostic quality with moderate artifacts; score of 2 and 1 (“Poor” and “Very poor”) indicates non-diagnostic quality. Good to excellent motion artifact were found in AJC images with upright CT in present study
