Abstract

- Diffuse and patchy myocardial uptake of Tc-99m PYP is well established in cases of ATTR-CA. - Chronic myocardial infarction leads to regional myocardial thinning and lack of vascular supply can present as regional sparing 'cold spot' on Tc-99m PYP imaging. - The absence of Tc-99m PYP uptake in vascular regions should raise the possibility of underlying scar.

转甲状腺素心脏淀粉样变性（ATTR-CA）和并发心肌梗死的焦磷酸锝（PYP）摄取区域差异：病例系列。

- 在 ATTR-CA 病例中，Tc-99m PYP 的弥漫性和斑片状心肌摄取已得到证实。- 慢性心肌梗死会导致区域性心肌变薄，血管供应不足会在 Tc-99m PYP 成像中表现为区域性稀疏 "冷斑"。- 如果血管区域没有 Tc-99m PYP 摄取，则应考虑潜在瘢痕的可能性。

期刊介绍： Journal of Nuclear Cardiology is the only journal in the world devoted to this dynamic and growing subspecialty. Physicians and technologists value the Journal not only for its peer-reviewed articles, but also for its timely discussions about the current and future role of nuclear cardiology. Original articles address all aspects of nuclear cardiology, including interpretation, diagnosis, imaging equipment, and use of radiopharmaceuticals. As the official publication of the American Society of Nuclear Cardiology, the Journal also brings readers the latest information emerging from the Society''s task forces and publishes guidelines and position papers as they are adopted.
