摘要
目的：研究急性胰腺炎不同胰腺病变区ＣＴ“时间－密度曲线”（Ｔ—Ｄ曲线）特征对各病变区作定性和定量诊断的作用。材料和方法：采用电子束ＣＴ（ＥＢＣＴ）Ｆｌｏｗ扫描程序扫描５条急性胰腺炎模型犬的胰腺正常区、水肿区和坏死区各１２个、１３个和１２个，对照病理分析所获得的Ｔ—Ｄ曲线和相应的ＣＴ值。结果：实验犬胰腺正常区、水肿区和坏死区Ｔ—Ｄ曲线的特征分别表现为“尖峰型”、“斜坡型”和“平坦型”。
Purpose:To study the role of time-density curve characteristics of different pancreatic pathologic areas in diagnosing acute pancreatitis on CT qualitatively and quantitatively.Materials and Methods:12 normal,13 edematous,and 12 necrotic areas of inflammatory pancreas in 5 model dogs were scanned by EBCT with flow program respectivelly and then compared with the pathology of the acquired time-density curves and CT attenuations.Results:Three types (“peak-type”,“slope-type”and“plain-type”)of acute pancreatitis which represented the time-density curve characteristics of normal,edematous,and necrotic areas of the inflammatory pancreas respectively could be shown on EBCT imagings.Conclusion:Acute pancreatitis could be diagnosed accurately by recognizing its different characteristic time-density curves qualitatively and quantitatively.
