Imaging of suspected somatostatin receptor positive tumors using 68Ga-HA-DOTATATE
Official title: 68Ga-HA-DOTATATE Imaging of Suspected Somatostatin Receptor Positive Tumors
Run by University of Alberta · NCT04888481 · Data updated 2026-11-12
This study is testing a new type of imaging called 68Ga-HA-DOTATATE PET/CT to see if it can better help people with suspected somatostatin receptor positive tumors compared to regular CT and MRI scans.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include patients with known or suspected somatostatin receptor positive tumors such as gastrointestinal, pancreatic, or pulmonary neuroendocrine tumors.
✕Probably not a fit
Patients who weigh over 225 kg or have conditions that prevent them from undergoing imaging will not benefit from this study.

What this trial studies
This study evaluates the safety and diagnostic effectiveness of 68Ga-HA-DOTATATE PET/CT imaging in patients with known or suspected somatostatin receptor positive tumors. It is a single center, non-randomized, non-blinded phase II prospective cohort study conducted at the University of Alberta Hospital. Up to 600 scans will be performed over a period of 6 years, including patients of all ages. The study will compare the efficacy of this imaging technique against standard CT and MRI based on a one-year follow-up clinical evaluation.
Why it matters
Potential benefit: If successful, this imaging technique could provide more accurate diagnoses for patients with neuroendocrine tumors, leading to better treatment decisions.
How similar studies have gone: Previous studies have shown that SSR PET imaging techniques can provide improved diagnostic accuracy compared to traditional imaging methods, indicating a promising approach.
