Cardiac planar radionuclide imaging using 99mTc-labeled bone seeking radiopharmaceuticals is used as a noninvasive diagnostic criterion in patients without detectable monoclonal protein. The visual assessment remains the main noninvasive criterion for the diagnosis. Medical therapy using tafamidis meglumine that binds to transthyretin and prevents amyloidogenesis, recently demonstrated a reduction in all-cause mortality and cardiovascular-related hospitalizations. As a consequence, there is a need for quantitative approaches that would be useful for diagnosis and prognosis assessment but also for the evaluation of patient therapeutic response.\n\nMaterials and methods: The investigators aim to include 35 patients with a suspected diagnosis of cardiac ATTR amyloidosis in whom a cardiac planar radionuclide imaging using 99mTc-labeled bone seeking radiopharmaceuticals is planned as part of routine noninvasive diagnosis work-up. Using a test-retest approach, the aim is to compare a quantitative method vs. conventional semi-quantitative approaches for the assessment of cardiac uptake of bone radiopharmaceuticals using new 3D CZT-based SPECT-CT cameras in patients with suspected cardiac ATTR amyloidosis. The investigators estimated that 20 patients will have a diagnosis of cardiac ATTR amyloidosis. In the latter patients, the aim is to evaluate the impact of 6-month therapy using tafamidis on quantitative and semi-quantitative assessment of cardiac uptake of bone radiopharmaceuticals Perspectives: This new non invasive imaging techniques for the quantitative assessment of the amyloid burden in patients with cardiac ATTR amyloidosis may help identify the responders and the patients who should benefit from dose intensification.",[82],"Amyloidosis Transthyretin","2025-01-29",{"date":85,"type":86},"2025-01-31","ACTUAL",{"date":88,"type":86},"2020-10-08",{"date":90,"type":76},"2025-06-15",{"name":5,"class":6},2]
