目的比较胰腺癌和炎性胰腺肿块的 CT 增强程度,研究胰腺各期的 CT 强化程度对该两种疾病的诊断价值。方法南京军区南京总医院85例胰腺癌和炎性胰腺肿块患者行平扫、胰期和延迟期增强扫描,测量胰腺肿块和正常胰腺组织的 CT 值,并进行统计学分析。结果 85例患者,胰腺癌66例,炎性胰腺肿块19例。在 CT 平扫、胰期增强、延迟期增强中,胰腺癌组肿块的 CT 值(HU)分别为34±7、54±10、61±14,其相对正常胰腺组织的 CT 值分别是42±6、105±12、77±10;炎性胰腺肿块的 CT 值分别是37±6、58±17、64±10,其相对正常胰腺组织的 CT 值分别是40±8、85±10、72±9。结论胰腺癌肿块和炎性胰腺肿块胰期增强 CT 值对两者的鉴别有一定局限;胰腺癌组和炎性胰腺肿块组肿块以外相对正常胰腺组织的胰期增强程度,前者强化明显,后者则强化中等。
Objective To compare the degree of CT enhancement in pancreatic cancer and inflammatory pancreatic mass and to evaluate the diagnostic value of CT enhancement in both stages of pancreatic cancer. Methods Eighty-five patients with pancreatic cancer and inflammatory pancreatic mass in Nanjing General Hospital of Nanjing Military Region were enrolled in this study. The CT scan values of pancreas and normal pancreatic tissue were measured by scanning, pancreas and delayed pancreatic tissue. Statistical analysis was performed. Results 85 patients, 66 cases of pancreatic cancer, 19 cases of inflammatory pancreatic mass. In CT scan, enhancement of pancreatic phase and enhancement of delayed phase, the CT values (HU) of pancreatic cancer mass were 34 ± 7, 54 ± 10 and 61 ± 14 respectively, and the CT values of the normal pancreatic tissue were 42 ± 6,105 ± 12,77 ± 10; CT value of inflammatory pancreas was 37 ± 6,58 ± 17,64 ± 10, the CT value of the relative normal pancreatic tissue were 40 ± 8,85 ± 10,72 ± 9. Conclusion Pancreatic cancer mass and inflammatory pancreatic mass enhanced pancreatic CT value of the two have some limitations; pancreatic cancer group and inflammatory pancreatic mass group of pancreatic tissue outside the normal pancreatic enhancement, the former enhanced significantly, the latter Then strengthen the medium.
