The rate of good-excellent scores ≥3
Image quality will be assessed by 2 radiologists using Likert-scale on a range from 1(poor) to 5(Excellent),and calculate the rate of ≥3 with FAS,PSS SS as the datasets analysis.
Time frame: From date of image reconstruction until the date of image reading completion, anticipated 1Week.
Objective outcome:Image Noise
Will use FAS,PSS,SS do the image noise (parameters record)datasets analysis.
Time frame: From Image reconstruction to image noise recording finished，estimate 1Week.
