摘要目的评价应用信号强度彩图(SICM)的增强MRI影像上病变的动态增强方式鉴别胰腺导管腺癌(PDAC)与肿块型胰腺炎(MFFP)的价值。方法研究包括41例临床病理证实的MFFP和144例手术证实的PDAC。实验室及MRI参数用以鉴别PDAC与MFFP,尤其评价SICM影像上病变的增强方式。应用分类系统分析(CTA),确定鉴别PDAC与MFFP的因素。结果在CTA所有参数中,不包括SICM影像上病变增强方式,胰腺导管堵塞程度及病变T1信号均匀程
Abstract Objective To evaluate the value of dynamic enhancement of lesions on enhanced MRI in the diagnosis of pancreatic ductal adenocarcinoma (PDAC) and mass pancreatitis (MFFP) by using SICM. Methods The study included 41 clinically and pathologically confirmed MFFP and 144 surgically confirmed PDACs. Laboratory and MRI parameters were used to identify PDAC and MFFP, in particular to evaluate the enhancement of lesions on SICM images. Classification system analysis (CTA) was used to determine the factors that discriminate between PDAC and MFFP. Results All the CTA parameters, including lesions on the SICM images, the extent of pancreatic duct blockage and lesion T1 signal uniformity
