The presence of subtype specific patterns of the DTI parameters for AL- and ATTR-amyloidosis should be investigated, in particular in comparison to nuclear imaging techniques where radiotracers used for technetium-labeled bone scintigraphy are found to have high sensitivity for ATTR [38], while 18F-florbetaben-PET has recently been shown to have a high sensitivity for AL-amyloidosis [39]. The gene discussed is TTR; the disease is axial length measurement.
