Optimizing PET Imaging with 18F-DOPA for Various Conditions

Official title: 18F-DOPA II - PET Imaging Optimization

Run by University of Alberta · NCT04706910 · Data updated 2026-11-12

This study is testing if a special imaging technique using 18F-DOPA can help doctors see and understand conditions like congenital hyperinsulinism, neuroblastoma, neuroendocrine tumors, Parkinson's disease, and Lewy body dementia better in both kids and adults.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include pediatric patients under 18 with congenital hyperinsulinism or neuroblastoma, and adults or pediatric patients with neuroendocrine tumors, Parkinson's disease, Lewy body dementia, or brain tumors.

Probably not a fit

Patients who are unable to provide consent, weigh over 225 kg, or cannot lie flat for the duration of the PET-CT session may not benefit from this study.

What this trial studies

This phase III interventional study focuses on optimizing 18F-DOPA PET/CT imaging for patients with congenital hyperinsulinism, neuroblastoma, neuroendocrine tumors, Parkinson's disease, and Lewy body dementia. The study will evaluate the imaging capabilities of 18F-DOPA, a tracer that mimics L-DOPA, to provide valuable insights into these conditions. It will involve both pediatric and adult patients, assessing the tracer's safety and efficacy in a local setting using advanced imaging technology. The primary objective is to enhance image quality, while secondary objectives include analyzing gallbladder activity patterns.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic imaging techniques that enhance the detection and management of various neurological and endocrine disorders.

How similar studies have gone: Previous studies have demonstrated the safety and efficacy of 18F-DOPA as a diagnostic tracer, indicating potential for success in this optimized imaging approach.
