About this study
Official title: Prospective, Single-center, Randomized Clinical Study Evaluating the Image Quality of Chest and Abdominal Scans Using Low-Dose Acquisition With Spectral Precise Image (SPI) Intelligent Denoising Versus Routine-Dose Acquisition Reconstructed With iDose4.
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
CT Radiation ScanRadiation
Use investigated CT do radiation scan
| Study group | Role | What they receive |
|---|---|---|
| Normal Dose | Other | Not described Receives: Radiation: CT Radiation Scan |
| Low Dose | Experimental | Not described Receives: Radiation: CT Radiation Scan |
What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: From date of image reconstruction until the date of image reading completion, anticipated 1Week.
Secondary outcomes (1)
Image Noise
Will use FAS,PSS,SS do the image noise (parameters record)datasets analysis.
Measured: From Image reconstruction to image noise recording finished，estimate 1Week.

Questions about this trial
What is this clinical trial studying?
A study testing CT Radiation Scan in people with Volunteer, run by Philips Clinical & Medical Affairs Global at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 11 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Yan Fu Hua (13661850380, Yfh11655@rjh.com.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The rate of good-excellent scores ≥3 (time frame: From date of image reconstruction until the date of image reading completion, anticipated 1Week.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Aug 2026; AzTrials last refreshed its copy on 1 Nov 2026.
