胰腺癌的早期诊断极为困难,约50%患者确诊时已有远处转移,35%患者肿瘤呈局部浸润性改变.外科手术为目前唯一可能治愈胰腺癌的治疗手段.因此,进一步提高胰腺癌早期诊断率,术前准确地分期,对于手术方案的制定及其预后的改善显得尤其重要.我们回顾性分析 MRI 联合磁共振血管成象(MR angiography,MRA)和磁共振胆胰管成象(MRcholangiopancreatography,MRCP)对胰腺癌的诊断价值及其术前分期的评估,并与螺旋 CT(SCT)和 ERCP 作对照分析.
Early diagnosis of pancreatic cancer is extremely difficult, about 50% of patients have been diagnosed distant metastasis, 35% of patients showed partial invasive tumor changes.Surgery is the only possible treatment of pancreatic cancer treatment.Therefore, to further enhance the early pancreatic cancer Diagnostic accuracy and staging accurately before surgery are particularly important for the development of surgical plans and the improvement of their prognosis.We retrospectively analyzed the correlation between MR angiography (MRA) and magnetic resonance cholangiopancreatography (MRcholangiopancreatography , MRCP) in diagnosis of pancreatic cancer and its preoperative staging, and compared with spiral CT (SCT) and ERCP.
