What this trial studies

This study evaluates the effectiveness of 68Ga-DOTA-FAPI-04 positron emission tomography/computed tomography (PET/CT) in diagnosing primary and metastatic lesions in various cancers, compared to the standard 18F-FDG PET/CT. Patients with suspected or diagnosed malignant tumors will undergo both types of scans, and the results will be analyzed for sensitivity, specificity, and overall diagnostic accuracy. The goal is to determine which imaging method provides better diagnostic information for cancer detection and monitoring.

Who should consider this trial

Good fit: Ideal candidates include adult patients aged 18 or older with suspected or diagnosed malignant tumors who can provide informed consent.

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

Why it matters

Potential benefit: If successful, this study could improve the accuracy of cancer diagnosis and monitoring, leading to better patient outcomes.

How similar studies have performed: Other studies have shown promising results with similar imaging techniques, suggesting potential for success in this approach.
