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
Running, but no longer taking on new participants.
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 Results may not be published yet.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.
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 study tested whether having patients stand during an ultrasound helps doctors see small liver tumors near the diaphragm that are often missed when lying down. Researchers scanned 95 people with confirmed liver lesions in three positions: standing, lying on their back, and lying on their left side. Two radiologists rated how well each position showed the tumor. The goal is to find a simple way to improve liver cancer detection without extra equipment or cost.

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 detection of small liver tumors by adding standing position to routine ultrasound, improving diagnosis without extra cost or risk.
What could go wrong
This is a small, completed observational study (95 people) comparing imaging positions, not testing a new treatment. Results may not apply to all patients or settings.
