本项研究的目的是评价多排探测器CT(MDCT)不同时期采集(平扫、动脉期和门脉期)于实验肠道模型上检测肠道出血的价值。该模型由7米长的猪小肠,及钻孔连接的注射管组成。肠管充盈水或密度为30～40HU的对比剂溶液并放置于模型内。模仿不同的出血部位和从0～0.75mL/min的不同速率出血
The purpose of this study was to evaluate the value of multi-detector CT (MDCT) acquisition of intestinal bleeding in experimental gut models collected at different periods (plain, arterial, and portal). The model consists of a 7-meter long pig intestine and a borehole connected syringe. The bowel is filled with water or contrast agent solution at a density of 30-40 HU and placed in the model. Simulate different bleeding sites and bleed at different rates from 0 to 0.75 mL / min
