目的：探讨胰腺恶性肿瘤的ＣＴ诊断。方法：分析了５４例胰腺恶性肿瘤的ＣＴ表现，其中４１例胰腺癌、８例胰囊腺癌、５例胰转移癌。年龄２７～８６岁。扫描自脾门部至十二指肠水平部，层厚１０ｍｍ，连续扫描，必要时追加５ｍｍ层厚及层距。结果：胰腺恶性肿瘤ＣＴ表现为胰腺软组织肿块；平扫呈等密度、低密度或不均匀密度，肿块强化不明显；胆管及胰管扩张；胰腺萎缩；血管受侵犯；脏器及淋巴结转移；周围脏器及组织的直接浸润，腹水等。结论：熟悉胰腺恶性肿瘤ＣＴ的直接及间接征象，利于胰腺恶性肿瘤的诊断及鉴别诊断。
Objective: To investigate the CT diagnosis of pancreatic malignancy. Methods: CT findings of 54 cases of pancreatic malignancies were analyzed. Among them, 41 cases of pancreatic cancer, 8 cases of pancreatic adenocarcinoma, and 5 cases of pancreatic metastasis. Age 27 to 86 years old. Scan from the splenic portal to the horizontal part of the duodenum with a layer thickness of 10mm, and scan continuously. If necessary, add 5mm layer thickness and layer spacing. RESULTS: CT findings of pancreatic malignancies were soft tissue masses of the pancreas; plain scans were of equal density, low density, or uneven density; tumors were not significantly enhanced; bile ducts and pancreatic ducts were dilated; pancreas was atrophied; blood vessels were invaded; organs and lymph node metastasis; Direct infiltration of organs and tissues, ascites, etc. Conclusion: To be familiar with the direct and indirect signs of pancreatic malignancies is conducive to the diagnosis and differential diagnosis of pancreatic malignancies.
