多层螺旋CT动态增强对小胰腺癌的诊断

Diagnosis of Small Pancreas Carcinoma with Multiple Layer Spiral CT of Kinesis Enhancement

目的探讨小胰腺癌的多层螺旋动态增强CT表现特点，旨在提高对该病的诊断。方法回顾性分析31例小胰腺癌的临床及CT影像资料，找出其特点。结果本组31例中，胰头癌24例，胰体癌6例，胰尾癌1例；肿瘤最大径在1.0-2.0 cm者28例，〈1.0 cm者3例；CT平扫呈低密度改变25例，等密度4例，水样密度2例。增强扫描均有不均匀性强化；另有胰周脂肪层消失5例；肝内外胆管扩张23例，合并胰管扩张20例；腔静脉、门静脉、肠系膜上动脉、腹主动脉及分支受累等11例；腹腔淋巴结肿大4例。结论多层螺旋CT动态增强扫描检查诊断早期胰腺癌是一种无创性方法，是临床诊断、治疗和评估预后最常用、最准确的影像学方法之一。

Objective To discuss the clinical manifestation of multiple layer spiral CT of kinesis enhancement on small pancreas carcinoma to improve the diagnosis. Methods The clinical and CT materials of 31 cases of such patient were analyzed retrospectively. Results There were 24 cases pancreas carcinoma of head, 6 cases of body and 1 case of tail. There were 28 cases diameter in 1.0 - 2.0 cm and 3 cases less than 1.0 cm. The low density change in plain scan was in 25 cases, equidensity in 4 cases and hydro - density in 2 cases. There were 5 cases of disappearance of fat tissue, 23 cases of bile duct dilation, 20 cases of pancreas duct dilation and 11 cases involved IVC, PC and abdominal OR. Conclusion The multiple layer spiral CT of kinesis enhancement on small pancreas carcinoma might be non - invasive, accuracy and common used in diagnosis, treatment and assessment of prognosis.
