英文摘要：

The latest technical development in the field of positron emission tomography/computed tomography (PET/CT) imaging has been the extension of the PET axial field-of-view. As a result of the increased number of detectors, the long axial field-of-view (LAFOV) PET systems are not only characterized by a larger anatomical coverage but also by a substantially improved sensitivity, compared with conventional short axial field-of-view PET systems. In clinical practice, this innovation has led to the following optimization: (1) improved overall image quality, (2) decreased duration of PET examinations, (3) decreased amount of radioactivity administered to the patient, or (4) a combination of any of the above. In this review, novel applications of LAFOV PET in oncology are highlighted and future directions are discussed.

正电子发射断层扫描/计算机断层扫描（PET/CT）成像领域的最新技术进展体现在PET轴向视野的扩展。由于探测器数量的增加，长轴向视野（LAFOV）PET系统不仅具有更大的解剖覆盖范围，与传统短轴向视野PET系统相比，其灵敏度也显著提升。在临床实践中，这一创新带来了以下优化：（1）整体图像质量提高，（2）PET检查时间缩短，（3）患者接受的放射性剂量减少，或（4）上述优势的任意组合。本综述重点探讨了LAFOV PET在肿瘤学中的创新应用，并对未来发展方向进行了讨论。
