About this trial
\[18F\]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
Qualifiers
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.
Adult patients (age ≥ 18 years);
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.
Scheduled to undergo a clinical Pan-Amyloid PET/CT scan as part of standard care or clinical evaluation.
Disqualifiers
Confirmed non-cardiac amyloidosis or other non-amyloid cardiac pathologies that could confound image interpretation.
Pregnancy or breastfeeding.
Any medical, psychological, or social condition that, in the opinion of the investigator, would compromise the subject's ability to participate fully or complete the study follow-up.
Adult subjects (age ≥ 18 years);
