摘　　要：目的:探讨CT增强长时间延迟扫描在腹膜假黏液瘤(PMP)患者CT腹膜癌指数(CT-PCI)评分中的价值研究。方法:回顾性分析2022年10月至2023年12月航天中心医院黏液瘤科102例经手术病理证实为腹膜假黏液瘤患者的术前CT图像,分别进行门脉期及长时间延迟期CT-PCI评分与术中的PCI评分对照,进行一致性分析。结果:使用Kappa系数评价CT-PCI与术中评分的一致性,CT增强扫描,PMP患者13个区CTPCI评分与术中PCI评分的一致性的Kappa值长时间延迟期均高于或等于门脉期;13个区长时间延迟期和门脉期CT-PCI评分与术中评分一致性平均Kappa值分别为(0.669±0.101)和(0.509±0.121),CT-PCI评分与术中PCI评分的一致性长时间延迟期显著高于门脉期。门脉期CT-PCI评分与术中PCI评分的一致性:1区,一致性较差;2、3、4、5、7、8、9、10和12区,一致性中等;0、6和11区,一致性较好。长时间延迟期CT-PCI评分与术中PCI评分的一致性:5、9、10和12区,一致性中等;0、1、2、4、7、8和11区,一致性较好;3区和6区,一致性非常好。门脉期、长时间延迟期的CT-PCI评分与术中PCI评分的一致性的对比,1区和3区差异显著;0、2、4、5、6、7和8区差异中等;9、10、11和12区一致性无明显差异。结论:通过CT增强的长时间延迟扫描方式,可有效提高术前CT-PCI评分的准确性。Objective:To explore the value of computed tomography(CT) enhanced long delayed scan in the CT peritoneal cancer index(CT-PCI) score of patients with pseudomyxoma peritonei(PMP).Methods:The preoperative CT images of 102 patients with confirmed peritoneal pseudomyxoma through surgery and pathology in the Mucinous Tumor Department of Aerospace Center Hospital from October 2022 to December 2023 were retrospectively analyzed.The CT-PCI scores of the portal venous and longdelayed phases with intraoperative PCI scores were separately compared and a consistency analysis was performed.Results:The consistency between CT-PCI and intraoperative scores was evaluated using the Kappa coefficient.The Kappa values for the consistency between CT-PCI scores in 13 zones of PMP patients during CT-enhanced long-delayed scans and intraoperative PCI scores of the long-delayed phase were higher than or equal to those of the portal venous phase.The average Kappa values for the consistency between CT-PCI and intraoperative scores in 13 zones of the long-delayed and portal venous phases were(0.669 ± 0.101)and(0.509 ± 0.121),respectively.The consistency between CT-PCI and intraoperative PCI scores was significantly higher in the long-delayed phase than that in the portal phase.The consistencies between the CT-PCI and intraoperative PCI scores in the portal venous phase are as follows:zone 1:poor consistency;zones 2,3,4,5,7,8,9,10,and 12:moderate consistency;zones 0,6,and 11:good consistency.The consistencies between the CT-PCI and intraoperative PCI scores in the long-delayed phase are as follows:zones 5,9,10,and 12:moderate consistency;zones 0,1,2,4,7,8,and 11:good consistency;zones 3 and 6:very good consistency.The consistencies between the CT-PCI and intraoperative PCI scores in the portal venous and delayed phases are as follows:zones 1 and 3:significant difference;zones 0,2,4,5,6,7,and 8:moderate difference;zones 9,10,11,and 12:no significant difference.Conclusion:The CT-enhanced delayed scanning method can effectively improve the ac
