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
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

Completed This study
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 Results may not be published yet.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.

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.

Summary

This study tested a new silicon photon counting CT scanner in 64 adults who already needed a CT scan. The goal was to see if the new scanner works well in a real hospital setting and produces good quality images. Participants had an extra scan using the new device, and researchers compared the images to standard scans and tracked any safety issues.

What this could mean

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

What this could lead to
If successful, this could lead to better, more detailed CT scans with less radiation for patients.
What could go wrong
This is a small, early feasibility study focused on data collection, not on proving health benefits. The new scanner may not show clear advantages over current CT technology.
