【摘要】 【目的】探讨CT平扫对急性胰腺炎的诊断价值。【方法】回顾性分析80例经临床证实急性胰腺炎病例的CT资料,观察其CT表现特征及范围。【结果】轻中型急性胰腺炎68例,大多数病人胰腺体积局部或弥漫性增大,胰腺密度均匀或不均匀,吉氏筋膜增厚,少数病人可无阳性CT表现;重型胰腺炎12例,胰腺体积增大,胰腺边界模糊,胰周脂肪间隙消失,胰周可见积液(小网膜囊和结肠间隙),胰腺坏死密度减低。【结论】CT平扫是诊断急性胰腺炎的简便、有效的方法,有助于急性胰腺炎的早期诊断及分型。更多还原

【Abstract】 【Objective】 To investigate the value of non-enhanced CT scan in the early diagnosis of acute pancreatitis.【Methods】 Eighty cases of acute pancreatitis confirmed clinically underwent CT non-enhanced scanning,and their CT features and lesion extents were retrospectively reviewed.【Results】 Sixty eight cases were slight or mild acute pancreatitis.In most patients,pancreas was swollen locally or diffusely and density of pancreas was homogeneous or heterogeneous,and peripancreatic fat became vague,and prerenal fascia was thickening.Minority patients had no abnormal finding.Twelve cases patients were severe acute pancreatitis.In these patients,pancreas was enlarged with low-attenuating necrosis,and peripancreatic fat became vague companied peripancreatic fluid collections(lesser sac,colonic space).【Conclusion】 Non-enhanced CT scan is a convenient and valuable method in the early diagnosis and classification of acute pancreatitis.更多还原
