摘　　要：xSPECT/CT较传统的SPECT/CT相比图像质量得到进一步改善,且定量指标标准摄取最大值(maximum standardized uptake value,SUVmax)可作为生物学标志物客观反映放射性核素浓聚水平,近年来被逐渐应用于临床研究中。本文对xSPECT/CT在重建算法方面的优势以及骨良恶性病变、非骨骼病变和深度学习技术的应用进行综述。xSPECT/CT offers further improvement in image quality compared to traditional SPECT/CT,and the quantitative metric maximum standardized uptake value(SUVmax)can serve as a biological marker objectively reflecting the concentration level of radioactive isotopes.In recent years,it has gradually been applied in clinical research.This article provides an overview of the advantages of xSPECT/CT in reconstruction algorithms,its applications in malignant bone lesions,benign bone lesions and non-skeletal lesions,and related deep learning techniques.
