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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 will test a new mobile 4D CBCT scanner that creates 3D images of lung lesions during a biopsy procedure. Researchers want to see if the images are clear and accurate enough to help doctors diagnose peripheral lung lesions. Fifty adults with small to medium-sized lung spots will be enrolled, and the scanner's images will be compared to standard CT scans.

What this could mean

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

Active substance
Mobile 4D CBCT imaging device
What this could lead to
If successful, this could provide clearer, real-time 3D images during lung biopsies, potentially improving diagnostic accuracy and reducing the need for repeat procedures.
What could go wrong
This is a small, early-stage validation study with only 50 participants. The technology may not prove significantly better than current imaging, and image quality depends on expert scoring, which is subjective.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Age \>18 years old. 2. Patients whose chest CT scans indicate the presence of peripheral pulmonary lesions and require further diagnosis via transbronchial lung biopsy (TBLB). 3. Lesion size: 8 mm \< longest diameter of lesion ≤ 50 mm. 4. Understands the study and has provided signed informed consent. Exclusion Criteria: 1. Contraindications to bronchoscopy are present. 2. Severe cardiopulmonary dysfunction or other conditions that may increase surgical risk. 3. The investigator considers that the patient has other conditions which make them unsuitable for participation in this study.
