What this trial studies

This research investigates the safety and effectiveness of a new dual receptor targeting PET radiotracer, 68Ga-FAPI-LM3, in patients with SSTR2 positive diseases. Participants will undergo both 68Ga-FAPI-LM3 and 18F-FDG PET/CT scans to assess the diagnostic accuracy of the new imaging agent compared to the standard. The study will evaluate biodistribution, radiation dosimetry, and the number of detected lesions. The goal is to determine if 68Ga-FAPI-LM3 provides better imaging results for these conditions.

Who should consider this trial

Good fit: Ideal candidates include adults with suspected or newly diagnosed malignant diseases that express FAP or SSTR2.

Not a fit: Patients with non-malignant diseases or those who are pregnant will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the accuracy of diagnosing SSTR2 positive diseases, leading to better patient management.

How similar studies have performed: While the use of PET imaging is well-established, the specific application of 68Ga-FAPI-LM3 for SSTR2 positive diseases is novel and has not been extensively tested.
