胰腺坏死是急性胰腺炎致命性并发症,发生率为5％～20％,可分为弥漫性、局灶性和多发性。为评价根据CT上胰腺无强化病变来确定胰腺坏死的准确性,作者回顾了26例急性胰腺炎的腹部CT表现。男18例,女8例,年龄18～64岁。全部病例均作平扫与增强扫描,其中常规扫描10例,螺旋扫描16例;在1周至26个月后均作了CT随访。CT诊断由两位有经验的放射医师独立与共同进行。结果显示,首次CT均表现为胰腺无强化区>3cm或胰 Pancreatic necrosis is a fatal complication of acute pancreatitis, the incidence rate of 5% to 20%, can be divided into diffuse, focal and multiple.
