Technetium-99m pyrophosphate single-photon emission computed tomography of the heart in familial amyloid
International Journal of Cardiology
|March 1, 1987
Abstract:
A patient with familial amyloid polyneuropathy and congestive heart failure underwent myocardial imaging using technetium-99m pyrophosphate. Planar scintigraphy showed an intense, diffuse biventricular uptake of the radiotracer. Single-photon emission computed tomography demonstrated an unevenly distributed uptake of the isotope. The greatest activity corresponded to regions with marked echocardiographic changes. Emission tomography may aid in assessing the degree and distribution of the infiltrative lesions in cardiac amyloidosis.
