What this trial studies

This observational study aims to assess the effectiveness of 18F-92/AV45 and 11C-PIB positron emission tomography/computed tomography (PET/CT) in diagnosing primary and metastatic lesions in patients with various Tau-related diseases. Participants, who are adults with suspected or newly diagnosed malignant tumors, will undergo PET/CT scans to quantify lesion uptake using the maximum standard uptake value (SUVmax). The study will calculate key diagnostic metrics such as sensitivity, specificity, and accuracy to determine the utility of these imaging techniques.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with suspected or newly diagnosed malignant tumors requiring Aβ PET/CT scans.

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 diagnostic accuracy for patients with Tau-related diseases, leading to better treatment decisions.

How similar studies have performed: Previous studies have shown promise in using PET imaging for similar diagnostic purposes, indicating potential success for this approach.
