急性胰腺炎的肝脏CT表现与病因探讨

CT performance of liver and pathogen investigation of acute pancreatitis

目的:观察急性胰腺炎患者肝脏异常影像学表现,并对其发生机理进行探讨。方法:回顾性分析28例急性胰腺炎患者的肝脏CT表现,采用双层螺旋CT机,重建层厚为10 mm。结果:28例患者中,22例CT显示肝脏密度明显减低,低于相同层面脾脏密度,占78.57%(22/28);5～20 d治疗后复查,68.18%(15/22)病例随病情好转而减轻,其中53.33%(8/15)完全恢复正常。结论:多层螺旋CT在清楚显示急性胰腺炎胰腺本身及其周围组织变化的同时亦可通过对肝脏密度减低的显示来反应肝脏实质的损害,为急性胰腺炎的早期诊断增添了新的诊断依据。

Objective To observe the abnormal manifestations of imaging in liver with patients suffering from acute pancreatitis and to study its mechanism.Method Retrospectively analyzed CT findings in liver of 28 patients with acute pancreatitis.Examined by GE Hispeed II double spiral CT,reconstruction slice thickness 10mm.Results In 28 cases,there were 22 cases that CT showed that liver density was significantly lower than spleen in the same slice,the percentage was 75%（22/28）.Having a treatment of 5-10 days,CT showed that there were 15cases that the density of liver was better than that before treatment,the percentage was 68.18%（15/22）,in these 15 cases,CT showed 8 patients′ density of liver was become normal,the percentage was 53.33%（8/15）.Conclusion Multi-slice spiral CT shows different imaging in pancreas and tissue around it clearly,at the same time CT can evaluate the liver damage through the density reducing degree.These add new early diagnosis for acute pancreatitis.
