NCT ID NCT07759050

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether chest and abdominal CT scans taken at a lower radiation dose, enhanced with a technology called Spectral Precise Image (SPI) intelligent denoising, can produce images as clear as standard-dose scans. About 80 healthy adult volunteers will receive both low-dose and routine-dose scans, and radiologists will compare image quality and noise levels. The goal is to see if lower radiation exposure can be used without compromising the clarity needed for accurate diagnosis.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Low-dose CT radiation scan with Spectral Precise Image (SPI) intelligent denoising
What this could lead to
If successful, this could enable lower radiation exposure for chest and abdominal CT scans without sacrificing image clarity, potentially improving patient safety.
What could go wrong
The trial is small (80 participants) and focuses on image quality rather than clinical outcomes, so results may not apply broadly or guarantee diagnostic accuracy.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 80 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Sep 2026

An estimate. Start dates often move.

Expected to finish

Sep 2027

An estimate. End dates often move.

Lead sponsor

A company

The lead sponsor is a pharmaceutical, biotech, or medical-device company.
