    [摘要]?目的?探討宝石能谱CT成像(gemstone?spectral?imaging，GSI)多参数在肝脏良恶性肿瘤中的变化及对手术可切除性的评估价值。方法?选取2018年5月至2021年8月湖州市第一人民医院收治的89例肝脏恶性肿瘤患者作为恶性组，同期的89例肝脏良性肿瘤患者作为良性组，进行回顾性分析。两组均行GSI检查，比较两组GSI参数[能谱曲线斜率(slope?of?spectral?Hu?curve，s-SHC)、动脉期标准碘浓度值(normalized?iodine?concentration，NIC)、门静脉期NIC、碘浓度差值(iodine?concentration?difference，ICD)、肝动脉碘分数(arterial?iodine?fraction，AIF)]，分析GSI参数对肝脏肿瘤癌变风险的影响及对肝脏良恶性肿瘤的诊断价值。将恶性组根据临床评估情况分为可切除患者(n=28)与不可切除患者(n=61)，对比两组患者的GSI参数水平，分析GSI参数对肝癌手术可切除性的评估价值。结果?恶性组s-SHC、动脉期NIC、门静脉期NIC、AIF均高于良性组，ICD低于良性组，差异均有统计学意义(P
