What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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.

Summary

This pilot study tests whether a new type of CT scanner, called photon-counting CT, can clearly show the urethra in prostate cancer patients without inserting a catheter. Currently, catheters are often needed to see the urethra during radiotherapy planning, which can be uncomfortable and carry infection risk. If the new scanner works, it could make treatment planning less invasive and help doctors better protect healthy tissues from radiation.

What this could mean

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

Active substance
Photon-counting CT imaging without catheter
What this could lead to
If successful, this approach could make radiotherapy planning more comfortable and less invasive by eliminating the need for a urinary catheter.
What could go wrong
This is a small pilot study with only 20 participants, so results may not apply broadly. The new CT technology may not provide clear enough images to replace catheter-based methods.
