目的:探讨与分析磁共振成像(MRI)动态增强定量参数与结直肠癌肝转移、大不列颠及爱尔兰结直肠病学协会(ACPGBI)评分的相关性.方法:选择2021年7月~2023年10月本院接诊的结直肠癌患者108例为观察对象,所有患者均给予MRI动态增强检查,并进行ACPGBI评分,采用手术判定患者的肝转移情况并进行相关性分析.结果:在108例患者中,术中判断为肝转移38例(肝转移组),占比35.19%,肝转移组与非肝转移组的一般资料对比无差异(P>0.05).肝转移组的ACPGBI评分显著高于非肝转移组(P<0.05).肝转移组的造影剂到达组织时间(T1 on set)、造影剂到达强化高峰的时间(TTP)都显著低于非转移组(P<0.05),最大型号强度值(SI)及其所对应的强化峰值(PV)、强化百分数(SI%)与非转移组相比都显著增高(P<0.05).Spearman分析显示结直肠癌患者的肝转移与ACPGBI评分、T1 on set、TTP、SI、PV、SI%都存在相关性(P<0.05).Logistic回归分析显示ACPGBI评分、T1 on set、TTP、SI、PV、SI%等都为导致结直肠癌肝转移的重要因素(P<0.05).结论:结直肠癌患者的肝转移发生率比较高,可使得ACPGBI评分增高,伴随有MRI动态增强定量参数异常,MRI动态增强定量参数与结直肠癌肝转移、ACPGBI评分存在相关性.
The Correlation Between Dynamic Enhanced Quantitative Parameters of MRI and Liver Metastasis and ACPGBI Score in Colorectal Cancer
Objective:To explore and analysis the correlation between dynamic enhanced quantitative parameters of MRI and liver metastasis of colorectal cancer,as well as the ACPGBI score.Methods:From July 2021 to October 2023,108 cases of patients with colorectal cancer who were diagnosed and treated at our hospital were selected as the research subjects.All patients were given dynamic contrast-enhanced MRI imaging and ACPGBI score,and the liver metastasis were determined by surgery and correlation analysis were conducted.Results:Among the 108 patients,38 patients were judged to have liver metastasis(liver metastasis group),accounting for 35.19%.There was no difference in general data between liver metastasis group and non-liver metastasis group(P>0.05).The ACPGBI score was significantly higher in the liver metastasis group than in the non-liver metastasis group(P<0.05).Both T1 on set and TTP were significantly lower in the liver metastatic group than in the non-metastatic group(P<0.05),and SI,PV,and SI%were all significantly higher compared with the non-metastatic group(P<0.05).Spearman Analysis showed an association of liver metastases with ACPGBI score,T1 on set,TTP,SI,PV,and SI%in colorectal cancer patients(P<0.05).Logistic regression analysis showed that the ACPGBI score,T1 on set,TTP,SI,PV,and SI%were all important factors leading to the liver metastasis of colorectal cancer(P<0.05).Conclusion:The incidence of liver metastasis in colorectal cancer patients is relatively high,which can lead to an increase in ACPGBI score,accompanied by abnormal dynamic enhanced quantitative parameters of MRI.There is a correlation between dynamic enhanced quantitative parameters of MRI and liver metastasis and ACPGBI score of colorectal cancer.
