摘要目的确定在动态CT上无间接征象的胰腺癌的临床、组织病理学及影像特征。方法纳入70例组织学证实为胰腺癌的病人(平均年龄70岁),所有病人在胰腺切除术前进行多期多层动态增强CT成像。评估每例病人的临床数据,包括糖类抗原19-9、等密度肿瘤的频次、间接征象的存在以及病理组织学结果,如肿瘤的位置、肿瘤的分期、镜下浸润生 Abstract Objective To determine the clinical, histopathological and imaging features of pancreatic cancer with indirect signs on dynamic CT. Methods Totally 70 patients with histologically confirmed pancreatic cancer (average age, 70 years) were enrolled in this study. All patients underwent multi-phase dynamic contrast-enhanced CT imaging before pancreatectomy. Clinical data of each patient were assessed, including carbohydrate antigen 19-9, frequency of iso-density tumors, the presence of indirect signs, and histopathological findings such as tumor location, tumor stage, microscopic infiltrates
