Clinical Study of Spectral CT

August 10, 2026 updated by: Philips Clinical & Medical Affairs Global

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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The rate of good-excellent scores ≥3
Time Frame: 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.
From date of image reconstruction until the date of image reading completion, anticipated 1Week.

Secondary Outcome Measures

Outcome Measure
Measure Description
