Diagnostic Performance and Prognostic Value of Extravascular Retention of 123I-Labeled Serum Amyloid P Component in Systemic Amyloidosis

Abstract

In AL amyloidosis, the EVR(24) is strongly associated with organ involvement and with prognosis and might serve as an indicator of the body amyloid load. Quantification of SAP retention using the EVR(24) has no additional value over (123)I-SAP scintigraphy in the detection of systemic amyloidosis.
