Amino acid transporter PET/CT imaging with MET/FET for AATS-related tumors

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 observational study enrolls adult patients with AATS-related diseases who are undergoing PET/CT with 11C- or 18F-MET/FET for initial assessment or for detection of recurrence. Lesion uptake is measured quantitatively using maximum standardized uptake value (SUVmax). Imaging results are compared with available clinical reference standards (for example MRI, CT, pathology, or tumor markers). The study reports diagnostic performance metrics including sensitivity, specificity, positive and negative predictive values, and overall accuracy.

4. patients who were able to provide informed consent (signed by participant, parent or legal representative) and assent according to the guidelines of the Clinical Research Ethics Committee.

Exclusion Criteria:
