The purpose of this study is to establish a physiological injection protocol according to body weight, in order to minimize amount of contrast medium and optimize contrast enhancement in pediatric patients performing thoracic CT examinations. The 80 pediatric patients under the age of 10 were studie...

조영제 주입 후 조영 증강의 정도와 효율을 조절하기위해 어떤 조치를 취하는가? | 마지막으로 조영제 주입 직후, 생리식염수의 투여는 조영 증강의 정도와 효율을 증가시키고 분산을 감소시킬 수 있다. 또한 흉부 CT에서 조영제 주입 용량을 감소시키고 상대정맥(Superior vena cava)과 쇄골하정맥(Subclavian artery)에서 발생하는 빔 경화 인공물을 감소시킨다. | |
혈관이나 연부조직의 조영 증강에 영향을 주는 중요한 요소는 무엇인가? | 몸무게는 조영제 주입량을 결정하는 매우 중요한 요소로서 조영 증강 정도를 결정하는 불가분의 관계에 있다. 더불어 혈관이나 연부조직의 조영 증강에 영향을 주는 중요한 요소이다. | |
환자의 신체 상태는 무엇으로 고려되는가? | 환자의 신체 상태는 혈관 및 장기의 실질 내 조영 증강에 영향을 미치는 가장 중요한 환자 인자로 고려되며, 조영 증강의 정도와 신체 습관의 역학 관계가 역 상관관계에 있다.[6] 특히 소아는 성인과 비교하여 빠른 심박수, 짧은 혈액 순환 시간, 작은 조직 구조물, 미성숙한 신기능을 지니고 있다. |
