目的研究比较不同充填剂与不同扫描体位在胃的螺旋CT扫描中的应用。方法分别对80例胃病患者采用不同的充填剂(水和低浓度泛影葡胺),与不同的体位(单体位和双体位),进行螺旋CT扫描,评价不同的充填剂与不同体位的优缺点。结果水作为充填剂组病灶显示情况明显优于低浓度泛影萄胺组且伪影少,选择双体位组的图像质量也明显优于常规体位组。结论胃螺旋CT扫描时应首选水作为充填剂,根据病变需要选择双体位,有利于图像质量的提高,从而提高临床诊断率。
Objective To compare the application of different filling agents and different scanning positions in spiral CT in the stomach. Methods Eighty patients with gastric diseases were treated with different filling agents (water and low concentration of diatrizoate), different body positions (single and double body positions), and spiral CT scans were performed to evaluate the effect of different filling agents and different body positions Advantages and disadvantages. Results Water as a filler group lesions showed significantly better than the low concentration of pan-amine group and the artifacts less, select the bi-position group image quality is also significantly better than the conventional position group. Conclusion As the filling agent, water should be the first choice in the gastric spiral CT scan. According to the need of the lesion, the double body position should be chosen to improve the image quality and improve the clinical diagnosis rate.
