MCQ : Nuclear-21
PET/CT images with [18F]-florbetaben.
Which is the best interpretation of these images?
A) ATTR Amyloidosis
B) AL Amyloidosis
C) Myocarditis
D) Sarcoidosis
Correct Answer is B) : AL Amyloidosis
The images show a diffuse cardiac uptake of [18F]-florbetaben, indicating the presence of cardiac AL amyloidosis. [18F]-florbetaben is one of the possible PET tracers that, according to the published results, can be used for the evaluation of AL Amyloidosis. Late static [18F]-florbetaben PET acquisitions can discriminate cardiac involvement due to AL amyloidosis from ATTR amyloidosis and from other non-CA conditions mimicking infiltrative disorders.
