摘要

摘要: 胰腺癌是一种高病死率的侵袭性恶性肿瘤。多层螺旋CT血管成像作为首选的胰腺成像手段,可评判胰周主要血管是否受侵、受侵范围和程度,为肿瘤分期、手术可切除性评估等提供可靠依据。MRI为CT的一种重要补充检查手段,对疾病诊断、肝转移和预后评估有重要的指导价值。胰腺癌血管侵犯情况是术前评估胰腺癌是否可切除的主要指标。淋巴结转移、远处转移、胰腺癌周围神经受侵及肝动脉变异等因素均会影响患者预后。指出胰腺癌患者的术前影像学评估对治疗方案制订、术式选择及预后判断具有指导意义。

Abstract: Pancreatic cancer is an invasive malignant tumor with a high mortality rate. As the preferred imaging method for pancreatic imaging,multi- slice CT angiography can evaluate the presence or absence,extent,and degree of invasion of peripancreatic major vessels to provide reliable evidence for tumor staging and surgical resectability evaluation. As an important supplementary method of CT,magnetic resonance imaging has an important guiding value in disease diagnosis,liver metastasis,and prognostic evaluation. Vascular invasion of pancreatic cancer is the main indicator for preoperative evaluation of respectability. Lymph node metastasis,distant metastasis,neural invasion of pancreatic cancer,and hepatic artery abnormalities are influencing factors for patients' prognosis. It is pointed out that preoperative imaging evaluation for patients with pancreatic cancer has guiding significance for the development of treatment regimens,selection of surgical procedures,and prognostic evaluation.
