【摘要】：目的:探討MRI多序列聯合檢查在胰腺癌術前分期的臨床應用價值。方法:回顧性分析25例經手術及病理證實的胰腺癌患者的MRI表現,并與手術及病理結果進行對照。所有患者進行T1WI、T2WI、MRCP以及多期動態(tài)增強序列檢查。結果:I期患者4例,Ⅱ患者12例,III期患者7例,IV期患者2例。胰腺癌Ⅱ期、III期診斷的靈敏性、特異性、準確率、陽性預測值與陰性預測值分別為91.7%與85.7%、92.3%與94.4%、92.0%與92.0%、91.7%與85.7%、92.3%與94.4%。MRI術前分期與術中及病理有較好的一致性(k=0.841),分期準確率為88.0%。結論:MRI、MRCP聯合多期動態(tài)增強序列檢查在胰腺癌的診斷及分期方面具有重要的臨床意義。
[Abstract]:Objective: to evaluate the clinical value of MRI multi-sequence combined examination in preoperative staging of pancreatic cancer. Methods: the MRI findings of 25 cases of pancreatic cancer confirmed by operation and pathology were analyzed retrospectively and compared with the results of operation and pathology. All patients were examined by T 1 WIN T 2 W I MRCP and multi-phase dynamic contrast enhanced sequence. Results there were 4 cases of stage 鈪，
