Abstract
Technetium-99m (99mTc)-labeled pyrophosphate (PYP) and 3,3-diphosphono-1,2-propanodicarboxylic acid (DPD) are currently the most established imaging agents for the diagnosis of cardiac amyloidosis, being able to distinguish light chain (AL) from transthyretin (TTR) type of the disease. We present a pattern of increased uptake in all soft tissues, sparing the organs that are usually most affected.
期刊介绍：
The Hellenic Journal of Nuclear Medicine published by the Hellenic Society of
Nuclear Medicine in Thessaloniki, aims to contribute to research, to education and
cover the scientific and professional interests of physicians, in the field of nuclear
medicine and in medicine in general. The journal may publish papers of nuclear
medicine and also papers that refer to related subjects as dosimetry, computer science,
targeting of gene expression, radioimmunoassay, radiation protection, biology, cell
trafficking, related historical brief reviews and other related subjects. Original papers
are preferred. The journal may after special agreement publish supplements covering
important subjects, dully reviewed and subscripted separately.
