Advances in the application of nuclear medicine imaging in the diagnosis and treatment of systematic light chain amyloidosis / 中华核医学与分子影像杂志

ABSTRACT

Systematic light chain (AL) amyloidosis is the most common forms of amyloidosis, which manifests as multiple organ system involvement, rapid progress, dire prognosis, difficult therapy and high mortality. Many patients may miss the optimal treatment as a result of not being diagnosed timely. Therefore, early diagnosis and assessment of involved extent of AL are clinical focuses. Related clinical studies have demonstrated that nuclear medicine imaging can be non-invasive in detecting amyloid deposits. It can not only early assess the extent and distribution of amyloid deposits in systemic AL amyloidosis, but also offer the indications for risk stratification, treatment response monitoring and prognosis assessment of the patients, especially for positron amyloidosis-specific tracers, which may have great prospects in the future. This review summarizes the application of nuclear medicine imaging in the systematic AL amyloidosis.
