摘要
目的 探讨中晚期胰腺癌的MRI诊断价值。方法 回顾分析16例中晚期胰腺癌患者的MRI检查资料。结果16例中,胰头部肿块8例,其中7例有明显的肝内外胆管扩张;胰腺体尾部肿块6例,均无胆道系统扩张;2例胰腺形态和大小正常,仅表现为肝内外胆管扩张。肿瘤T1WI表现为略低于肝实质信号,T2WI表现为略高于肝实质信号。扩张的胆管T1WI表现为均匀低信号,T2WI表现为均匀明亮的高信号。5例患者可见下腔静脉、肠系膜上动静脉、脾动静脉受侵。4例肝内转移,1例肺转移,转移灶信号与原发灶类似。结论 MRI对中晚期胰腺癌诊断和分期、判断手术可行性及患者预后具有重要价值。
Objective To study the diagnostic value of MRI in moderatelyand far advanced pancreatic carcinoma. Methods The MRI fingings of 16cases of moderately or far advanced pacreatic carcinoma were studiedretrospectively. Results Pancreatic carcinoma occurred to the head of thepancreas in 8 cases out of the 16.Severe cholangiectasis was found in 7 outof the 8 cases.Pancreatic carcinoma occurred to the body and tail of thepancreas in 6 cases out of the 16 and no cholangiectasis could be found inthem.No mass existed in the pancreas of 2 cases out of the 16 but onlycholangiectasis was present in them..Pancreatic carcinoma showed slightlylower signal on T1WI and slightly higher on T2WI than that of hepaticparenchyma.Cholangiectasis showed homogeneous long T1 and long T2signal.The inferior vena cana and the superior mesenteric artery and veinwere invaded by the carcinoma in 5 cases.Metastasis of the carcinoma to theliver was found in cases and to the lungs in 1.The signals of the metastaticcarcinoma were similar to those of the primary focus. Conclusion MRIscanning is an important procedure for the diagnosis and the determinationof surgical intervention and prognosis in patients with moderately or faradvanced pancreatic carcinoma.[
