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 Results may not be published yet.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.

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 trial tests whether contrast-enhanced ultrasound (CEUS) using Lumason can detect kidney scarring as accurately as the standard DMSA scan, but without radiation. Children and young adults scheduled for a DMSA scan will receive an additional CEUS exam. If CEUS proves reliable, it could offer a safer, less expensive alternative for diagnosing kidney scarring.

What this could mean

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

Active substance
an ultrasound contrast agent called Lumason (sulfur hexafluoride lipid microspheres)
What this could lead to
If successful, this could offer a radiation-free, safer way to detect kidney scarring, potentially replacing DMSA scans and avoiding sedation and allergic reactions.
What could go wrong
This is an early-phase trial with only 70 participants. The contrast-enhanced ultrasound may not be as accurate as the standard DMSA scan, and results may not apply to all patients.
