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 Results may not be published yet.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.

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 compares CT and MRI scans to see which more accurately determines if bladder cancer has spread into the muscle layer. About 150 adults with newly diagnosed bladder cancer will receive both scans before standard surgery. The results will be checked against tissue samples to measure accuracy.

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 show that MRI is more accurate than CT for staging bladder cancer, helping doctors choose the right treatment without unnecessary surgery.
What could go wrong
This is a diagnostic accuracy study, not a treatment trial. It may find that MRI is not significantly better than CT, or results may not apply to all patients.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population consists of adult patients with newly diagnosed bladder cancer identified on cystoscopy at a tertiary referral hospital. Eligible participants are patients planned for transurethral resection of the bladder tumor (TURBT) and/or cystectomy as part of standard clinical care, and who are able to undergo both contrast-enhanced computed tomography (CT) and multiparametric magnetic resonance imaging (MRI) prior to definitive histopathological assessment. Patients are included irrespective of tumor stage or grade at presentation, provided that imaging is performed within the defined preoperative diagnostic pathway. Patients with prior bladder cancer treatment or contraindications to imaging are excluded.
