Cutting radiation in CT scans: a new test of Ultra-Low-Dose imaging
NCT ID NCT05840003
First seen Aug 14, 2026 · Last updated Aug 14, 2026
Summary
This trial tests whether an ultra-low-dose CT scan, using a new image reconstruction algorithm, can produce images good enough for diagnosing lung, abdominal-pelvic, and bone lesions, compared to a standard-dose CT scan. About 116 adults will receive both scans as part of their usual care. The goal is to see if the ultra-low-dose images are of sufficient quality to be used routinely, potentially reducing radiation exposure without compromising diagnostic accuracy.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Ultra-Low-Dose thoraco-abdominopelvic computed tomography (CT) scan using the Precise Image reconstruction algorithm
- What this could lead to
- If ultra-low-dose CT scans prove as good as standard scans, patients could undergo imaging with far less radiation exposure, reducing long-term risks.
- What could go wrong
- The trial is relatively small and early, and image quality may not be sufficient for all diagnoses. There is also a risk that the ultra-low-dose scans miss subtle lesions.
