胃肠钡剂检查发现有张力较高 ,蠕动增强 ,甚至呈痉挛状态 ,而应用维生素K制剂使消化道平滑肌张力减低、蠕动减弱、管腔舒张、粘膜展平等原理 ,进行胃肠道低张双重对比造影检查法 (以下简称双重法 )诊断 ,已成为放射科普通X线的成熟检查项目。在基层医疗单位中低张造影也逐渐应 Gastrointestinal barium examination found that high tension, increased peristalsis, and even spasticity, and the application of vitamin K preparations to reduce digestive tract smooth muscle tension, decreased peristalsis, lumen diastolic mucosal flat equal principle, low GI double Contrast contrast imaging method (hereinafter referred to as double method) diagnosis, radiology has become a regular X-ray mature inspection items. In primary health care units in low-resolution angiography should gradually
