体位因素对小肠MSCT、MRI成像质量的影响

The Effect of Position Factor on Small Intestine's Image Quality of MSCT or MRI

目的探讨MSCT、MRI检查前肠道准备及扫描时患者体位对小肠成像质量的影响。方法将112例行MSCT、MRI检查的患者随机分为A、B2组,A组(48例)患者取右前俯卧位,B组(64例)患者采用常规仰卧位。比较2组患者在MSCT、MRI成像中小肠的成像质量。结果 A组患者在行MSCT、MRI检查时,小肠的成像质量优于B组患者(χ2=10.18,p<0.05),差别有统计学意义。结论行小肠MSCT或MRI检查时采取右前俯卧位,有利于小肠达到满意的充盈效果,提高诊断的准确率。

Objective ：To figure out the best position for the small intestine＇s image quality of MSCT or MRI.Methods： 112 patients who were checked by MSCT or MRI,were randomly divided into Group A and Group B. 48 patients in Group A took right front prone position,while 64 patients took the regular supine position when they were checked by MSCT or MRI.The small intestine＇s image quality was compared with the two groups.Results：The small tntestine＇s image quality of MSCT or MRI in patients of Group A is better than that of the patients in Group B （χ^2= 10.18 ,p 〈0.05）.Conclusion：It was suggested that taking right front prone position while patients were checked by MSCT or MRI might help get better image quality of small intestine and improve diagnoses.
