Using Hydroxyephedrine PET/CT to Diagnose Sympathetic Nervous System Diseases

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

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.

Why it matters
