Using PET/MR to identify types of kidney tumors

Prospective Observational Study Using PET/MR for Characterization of Renal Masses (RMs)

Observational University of Texas Southwestern Medical Center · NCT06076538

This study is testing if a new type of imaging can help doctors tell the difference between aggressive and harmless kidney tumors in people with certain kidney masses.

What this trial studies

This observational study aims to evaluate the effectiveness of Fludeoxyglucose (18F) PET/MR imaging in distinguishing between aggressive and benign kidney tumors. With the rising incidence of incidental renal masses detected through imaging, the study seeks to address the issue of over-treatment by providing a more accurate diagnostic tool. Participants will include individuals with solid renal masses measuring between 2 to 7 cm, and the study will assess the imaging's ability to differentiate tumor types compared to standard radiologic scans.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 with a known solid renal mass measuring between 2 to 7 cm.

Not a fit: Patients with prior treatment of the renal mass or those with contraindications to MRI or PET will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could reduce unnecessary surgeries and treatments for patients with benign or indolent kidney tumors.

How similar studies have performed: Other studies have shown promise in using advanced imaging techniques for tumor characterization, but this specific approach with PET/MR is relatively novel.
