摘要
目的分析胰腺癌的多层螺旋CT影像学表现。方法对66例胰腺癌患者行多层螺旋CT多期容积扫描并薄层重建,分析肿瘤分布、形态、大小、密度、CT增强表现、与周围血管的关系、周围脂肪受侵情况、淋巴结及其他脏器转移情况。结果肿瘤分布于胰腺头及钩突27例,颈部12例,体部19例,尾部10例。肿瘤大小为1.0～3.0 cm 12例,3.0 cm以上54例。63例形态不规则。平扫低密度14例,等密度50例,高密度0例,混合密度2例。动脉期无强化49例,中等度强化15例,明显强化2例。门静脉期轻度强化13例,中等度强化且强化不均匀63例。45例胰腺导管扩张,21例胰腺导管无扩张。57例胰腺周围脂肪间隙不清楚。胰腺周围、腹腔、腹膜后淋巴结转移有无转移33例,无转移33例。39例患者发生肝脏、肺等远处脏器转移。61例不同程度累及胰周血管。结论胰腺癌的多层螺旋CT表现为:肿瘤常分布于胰头及钩突,形态不规则,多数大于3.0 cm,胰腺导管扩张常见,平扫大多数为等密度,增强动脉期多数为无强化,门静脉期轻中度强化,周围脂肪间隙及胰周血管多受累。
Objective To study muhislice CT image of pancreatic cancer. Methods 66 cases of pancreatic cancer patients underwent MDCT scan and phase volume thin layer reconstruction, tumor distribution, morphology, size, density, the relationship between CT enhancement performance, and its around vessel, fat around the invasion, metastasis lymph nodes and other organs were analysed. Results Tumor in the pancreas head and hook were 27 cases, tumor in the pancreas neck 12 cases, tumor in the pancreas body 19 cases,tumor in the pancreas tail 10 cases. Tumor size of 12 cases was 1.0 - 3.0 cm,3.0 cm above was 54 cases. 63 cases of irregular. Scan 14 cases of low density, density of 50 cases, high density 0 cases and mixed density in 2 cases. No arterial enhancement in 49 cases, moderate degree of 15 cases, significantly enhanced in 2 cases. 13 cases of portal vein phase of mild reinforcement, moderate degree of uneven strengthening and the strengthening of 63 cases. 45 cases of pancreatic duct expansion,21 cases of pancreatic duct expansion. 57 cases of pancreatic fat around the gap was not clear. Around the pancreas ,abdominal and retroperitoneal lymph node metastasis for 33 cases, no transfer of 33 cases. 39 patients with distant organs such as liver,lung metastasis. 61 cases with different degree of involvement of peripancreatic blood vessels. Conclusion Muhislice CT manifestation of pancreatic cancer：tumor is often located in the pancreatic head and the hook, its shape is irregular, most more than 3.0 cm,pancreatic duct expansion is common, scan mostly is density, enhanced mostly no arterial enhancement, portal venous phase mild-to-moderate reinforcement,fat gap and peripancreatic blood vessels around more involvement.
