Abstract

Stress images are on the left and rest images are on the right. The top row is a TTP subject and the bottom row is a control subject. The color maps show myocardial blood flow (MBF) in ml/g/min with brighter colors indicating higher perfusion. Stress imaging of the TTP patient shows decreased MBF compared with control, primarily noted in the subendocardium. The rest images do not show any significant difference in MBF at rest.

血栓性血小板减少性紫癜（TTP）幸存者在心脏MRI上表现出应激灌注受损

压力图像在左边，休息图像在右边。上面一行是一个TTP主题，下面一行是一个控制主题。彩色图显示心肌血流量（MBF）（ml/g/min），颜色越亮表示灌注越高。与对照组相比，TTP患者的应激成像显示MBF下降，主要表现在心内膜下。其余图像显示静止时MBF无显著差异。

期刊介绍： The American Journal of Hematology offers extensive coverage of experimental and clinical aspects of blood diseases in humans and animal models. The journal publishes original contributions in both non-malignant and malignant hematological diseases, encompassing clinical and basic studies in areas such as hemostasis, thrombosis, immunology, blood banking, and stem cell biology. Clinical translational reports highlighting innovative therapeutic approaches for the diagnosis and treatment of hematological diseases are actively encouraged.The American Journal of Hematology features regular original laboratory and clinical research articles, brief research reports, critical reviews, images in hematology, as well as letters and correspondence.
