SSTR-RADS Version 1.0 as a Reporting System for SSTR PET Imaging and Selection of Potential PRRT Candidates: A Proposed Standardization Framework

摘要

Reliable standards and criteria for somatostatin receptor (SSTR) PET are still lacking. We herein propose a structured reporting system on a 5-point scale for SSTR PET imaging, titled SSTR-RADS version 1.0, which might serve as a standardized assessment for both diagnosis and treatment planning in neuroendocrine tumors. SSTR-RADS could guide the imaging specialist in interpreting SSTR PET scans, facilitate communication with the referring clinician so that appropriate workup for equivocal findings is pursued, and serve as a reliable tool for patient selection for planned peptide receptor radionuclide therapy.
