Abstract

The purpose of this paper is to provide an overview of the cutting-edge applications of artificial intelligence (AI) technology in total-body positron emission tomography/computed tomography (PET/CT) scanning technology and its profound impact on the field of medical imaging. The introduction of total-body PET/CT scanners marked a major breakthrough in medical imaging, as their superior sensitivity and ultralong axial fields of view allowed for high-quality PET images of the entire body to be obtained in a single scan, greatly enhancing the efficiency and accuracy of diagnoses. However, this advancement is accompanied by the challenges of increasing data volumes and data complexity levels, which pose severe challenges for traditional image processing and analysis methods. Given the excellent ability of AI technology to process massive and high-dimensional data, the combination of AI technology and ultrasensitive PET/CT can be considered a complementary match, opening a new path for rapidly improving the efficiency of the PET-based medical diagnosis process. Recently, AI technology has demonstrated extraordinary potential in several key areas related to total-body PET/CT, including radiation dose reductions, dynamic parametric imaging refinements, quantitative analysis accuracy improvements, and significant image quality enhancements. The accelerated adoption of AI in clinical practice is of particular interest and is directly driven by the rapid progress made by AI technologies in terms of interpretability; i.e., the decision-making processes of algorithms and models have become more transparent and understandable. In the future, we believe that AI technology will fundamentally reshape the use of PET/CT, not only playing a more critical role in clinical diagnoses but also facilitating the customization and implementation of personalized healthcare solutions, providing patients with safer, more accurate, and more efficient healthcare experiences.

全身 PET/CT:人工智能的作用?
本文旨在概述人工智能(AI)技术在全身正电子发射断层扫描/计算机断层扫描(PET/CT)技术中的前沿应用及其对医学成像领域的深远影响。全身正电子发射计算机断层扫描/计算机断层成像扫描仪的问世标志着医学成像领域的重大突破,因为它具有超高的灵敏度和超长的轴向视野,一次扫描即可获得全身的高质量正电子发射计算机断层扫描图像,大大提高了诊断的效率和准确性。然而,在取得进步的同时,数据量和数据复杂度也在不断增加,这给传统的图像处理和分析方法带来了严峻的挑战。鉴于人工智能技术在处理海量高维数据方面的卓越能力,人工智能技术与超灵敏 PET/CT 的结合可谓相得益彰,为快速提高基于 PET 的医疗诊断效率开辟了一条新路。最近,人工智能技术已在与全身 PET/CT 相关的几个关键领域展现出非凡的潜力,包括辐射剂量的降低、动态参数成像的完善、定量分析准确性的提高以及图像质量的显著提升。人工智能技术在可解释性方面的快速进步直接推动了人工智能在临床实践中的加速应用,即算法和模型的决策过程变得更加透明和易于理解。未来,我们相信人工智能技术将从根本上重塑 PET/CT 的应用,不仅在临床诊断中发挥更关键的作用,还将促进个性化医疗解决方案的定制和实施,为患者提供更安全、更准确、更高效的医疗体验。
