What this trial studies

This observational study evaluates the effectiveness of 68Ga/18F-Exendin 4 positron emission tomography/computed tomography (PET/CT) in diagnosing primary and metastatic lesions in patients with GLP-1 receptor-related diseases. Participants include adults with suspected or newly diagnosed malignant tumors who are scheduled for an Exendin 4 PET/CT scan. The study measures the uptake of lesions using the maximum standard uptake value (SUVmax) and calculates various diagnostic metrics such as sensitivity and specificity.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with suspected or diagnosed malignant tumors related to GLP-1 receptor activity.

Not a fit: Patients with non-malignant lesions or those unable to provide informed consent will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the accuracy of diagnosing GLP-1 receptor-related tumors, leading to better patient management.

How similar studies have performed: While this approach is innovative, similar studies using PET/CT imaging for tumor diagnosis have shown promising results.
