CT에서 조영제 주입검사와 Non Contrast IVP 검사의 연구

A Study of Non-contrast IVP and Contrast Media Injection Examination in CT

Purpose : The purpose is to obtain accuracy and convenience of diagnosis and economical examinations in CT and IVP as injecting contrast media only one time for patients. also, we purpose reducing NPO(Nothing per oral) time at least 6 hours as examining these examinations without twice contrast media injection. Object and Method : Normally, it takes 2 days for patient to examine these examinations. sometimes, patient to need these examinations for one day used to examine IVP first and then they examined CT examination after 2 liters normal saline injection for 6 hours to be hydrated because of limitation of artifact in pelvis scan images during CT examination. or after CT examination using contrast media, patient examine KUB. projection at time order(For example 5min, 10min, 15min, 30min, lhr, 2hr, 3hr, 4hr……). We examined these above examinations to patient needed both examinations. 1. Doing NPO such as IVP to patient. 2. Reserving both examinations at similar time as much[far] as possible. 3. First, examining scout images in IVP room and then moving patient to CT room and examining IVP directly after CT examination using contrast media. 4. Notifying patient of coming back after CT examinations right away. 5. After CT examinations, laying down patient on the projection table and compressing their lower abdomen in a compression band and then examining IVP following routine procedure. Result : After following above method, we can provide more clear IVP images and high quality medical services with patient promptly and economically as examining these examinations at similar time. expecially, we can help operation plan for pre-operation patient because of reduce of examination time caused quick diagnosis. Conclusion : We have had clear contrast images in both examinations easily and quickly. also we had reduced NPO time at least 6 hours as injecting contrast media only one time during both examinations.
