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”。结论：通过辨认不同病变区Ｔ—Ｄ曲线特征可对急性胰腺炎作精确的定性和定量诊断
Objective: To study the role of CT “time-density curve” (T-D curve) in different pancreatic lesions of acute pancreatitis in the qualitative and quantitative diagnosis of various lesions. MATERIALS AND METHODS: Twelve, thirteen and twelve pancreatic normal, edematous and necrotic regions of 5 acute pancreatitis models were scanned by EBCT Flow scanning program. The T- D curve and the corresponding CT value. Results: The T-D curves in normal, edematous and necrotic areas in experimental dogs showed “peak type”, “slope type” and “flat type” respectively. CONCLUSIONS: Accurate qualitative and quantitative diagnosis of acute pancreatitis can be performed by identifying the T-D curve characteristics of different lesion areas
