[18F]FT8 PET Imaging in Immunoglobulin Light Chain Amyloidosis
Trial Parameters
Brief Summary
\[18F\]FT8, a derivative of 1-(4-pyridyl)-4-piperazinyl arene (\[18F\]TPZA), exhibits high affinity for AL amyloid in myocardial tissue sections and shows no significant binding to transthyretin amyloid. By comparing its diagnostic performance against established clinical methods, including echocardiography, contrast-enhanced MRI, and relevant laboratory tests, this study aims to establish \[18F\]FT8 as the basis for a robust PET protocol for the direct visualization and differential diagnosis of AL amyloidosis . The study preimarily evaluates the safety and diagnostic efficacy of \[18F\]FT8 PET imaging in human subjects.
Eligibility Criteria
1. Subject Recruitment Participants will be recruited from outpatients and/or inpatient populations of the Hematology Department at Tianjin Medical University General Hospital. The principal investigator and collaborating hematologists will ensure consistent application of diagnosis and enrollment criteria based on standardized guidelines. The planned enrollment includes 20 patients with systemic amyloidosis (including cardiac involvement) and 5 healthy volunteers. 2. Amyloidosis Patients: 2.1 Inclusion Criteria: Subjects must meet all of the following criteria: 1. Adult patients (age ≥ 18 years); 2. Suspected, newly diagnosed, or previously diagnosed with cardiac amyloidosis, with supporting evidence from one or more of the following: cardiac MRI, contrast-enhanced CT, serum biomarkers (e.g., NT-proBNP, Troponin), or histopathological confirmation of amyloidosis. 3. Scheduled to undergo a clinical Pan-Amyloid PET/CT scan as part of standard care or clinical evaluation. 4. Able to unde
