What this trial studies

This study evaluates the effectiveness of 11C/18F-HED positron emission tomography/computed tomography (PET/CT) in diagnosing primary and metastatic lesions in patients with various sympathetic nerve-related diseases. Participants, who are adults with suspected or diagnosed malignant tumors, undergo PET/CT scans to assess lesion uptake and quantify results using the maximum standard uptake value (SUVmax). The study aims to calculate the sensitivity, specificity, and accuracy of this imaging technique for better diagnosis and management of these conditions.

Who should consider this trial

Good fit: Ideal candidates include adult patients aged 18 and older with suspected or newly diagnosed malignant tumors.

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 enhance diagnostic accuracy for patients with sympathetic nervous system diseases, leading to improved treatment outcomes.

How similar studies have performed: Other studies have shown promising results using PET/CT imaging for similar diagnostic purposes, indicating potential success for this approach.
