The purpose of this article is to describe the clinical applications of a total-body PET scanner and discuss future expectations. PET has been widely used in the fields of oncology, neurology, and cardiology. However, current PET scanners have limitations, including long scanning time, low signal-to-noise ratio, and high dose of ionizing radiation. Total-body PET with a long scan range provides solutions to these problems, markedly increasing the sensitivity of the system.
本文旨在描述全身 PET 扫描仪的临床应用，并探讨未来的期望。PET 在肿瘤学、神经学和心脏病学等领域得到了广泛应用。然而，目前的 PET 扫描仪存在一些局限性，包括扫描时间长、信噪比低和电离辐射剂量高。具有长扫描范围的全身 PET 为这些问题提供了解决方案，显著提高了系统的灵敏度。
