Conditions
Brief summary
This study will prospective enroll 80 subjects to evaluate the comparison of image quality, proportion of high-quality images, and image noise between the Spectral Precise Image (SPI) intelligent denoising for low-dose scans on the Spectral CT Verida system and iDose4 reconstructions after low-dose and routine-dose scans.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The rate of good-excellent scores ≥3 | From date of image reconstruction until the date of image reading completion, anticipated 1Week. | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Objective outcome:Image Noise | From Image reconstruction to image noise recording finished，estimate 1Week. | Will use FAS,PSS,SS do the image noise (parameters record)datasets analysis. |
