【摘要】：目的:探討MRI多序列聯(lián)合檢查在胰腺癌術(shù)前分期的臨床應(yīng)用價值。方法:回顧性分析25例經(jīng)手術(shù)及病理證實的胰腺癌患者的MRI表現(xiàn),并與手術(shù)及病理結(jié)果進(jìn)行對照。所有患者進(jìn)行T1WI、T2WI、MRCP以及多期動態(tài)增強序列檢查。結(jié)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(zhǔn)確率、陽性預(yù)測值與陰性預(yù)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(shù)前分期與術(shù)中及病理有較好的一致性(k=0.841),分期準(zhǔn)確率為88.0%。結(jié)論:MRI、MRCP聯(lián)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，
