Is this trial a fit for you?

Likely a good fit

Adults with newly diagnosed bladder cancer who are scheduled for TURBT or cystectomy within 6 weeks and can receive both CT and MRI.

Probably not a fit

Patients unable to undergo MRI or iodinated contrast, or those with lesions that are non-malignant or located outside the bladder, may not benefit from the findings.

What this trial studies

This prospective, single-center diagnostic study compares two imaging methods—contrast-enhanced CT and multiparametric MRI using VI-RADS—for local staging of newly diagnosed bladder cancer. Each participant undergoes both imaging tests before TURBT or cystectomy, and histopathology serves as the reference standard. Two radiologists read the images in blinded fashion, and the results are analyzed with paired statistics to compare accuracy and interobserver agreement. The goal is to determine which modality or approach provides more reliable information to guide treatment decisions between non-muscle-invasive and muscle-invasive disease.

Why it matters

Potential benefit: If successful, the study could indicate which imaging approach offers higher accuracy for local staging, potentially influencing preoperative planning and patient management.

How similar studies have gone: Prior retrospective and meta-analytic work suggested MRI with VI-RADS may outperform CT for local staging, but prospective paired evidence is limited.
