简要总结
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 chest and abdomen low-dose and routine-dose scans.

结局指标
主要结局
The rate of good-excellent scores ≥3
时间窗: 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.
次要结局
- Image Noise(From Image reconstruction to image noise recording finished，estimate 1Week.)
