Abstract

The objective of this study was to detect the fragments generated during IV (intravenous) catheter injection of contrast medium and drug administration in a clinical setting and removal was performed by experimentally producing a phantom, and to compare the radiography, ultrasonography, and multi-detector computed tomography (MDCT) imaging and radiation dose. A 1 cm fragment of an 18 gage Teflon$^{(R)}$ IV catheter with saline was inserted into the IV control line. Radiography, CT, and ultrasonography were performed and radiography and CT dose were calculated. CT and ultrasonography showed an IV catheter fragment clinically and radiography showed no visible difference in the ability to provide a useful image of an IV catheter fragment modality (p >.05). Radiography of effective dose ($0.2139mSv{\cdot}Gy^{-1}{\cdot}cm^{-2}$) form DAP DAP ($0.93{\mu}Gy{\cdot}m^2 $), and dose length product (DLP) ($201mGy{\cdot}cm$) to effective dose was calculated as 0.483 mSv. IV catheter fragment were detected of radiography, ultrasonography and CT. These results can be obtained by menas of an excellent IV catheter fragment of detection capability CT. However, CT is followed by radiation exposure. IV catheter fragment confirming the position and information recommend an ultrasonography.

조영증강을 위해 조영제를 정맥내 카테터로 주입하는 과정에서 정맥태 카테터 조각을 검출하고 제거하기 위해 식염수와 18 게이지 테프론 IV 카테터의 1cm 조각을 삽입하여 팬텀을 제작하여 엑스선, 초음파 및 CT 영상을 비교하고자 한다. 엑스선, 초음파 및 CT에서 정맥내 카테터 조각을 임상적으로 유용하게 보였고, 조각의 묘출 능력에는 차이가 유의한 차이가 없었다.(p >.05). 방사선 선량은 엑스선에서 DAP ($0.93{\mu}Gy{\cdot}m^2$) 및 유효선량 ($0.2139mSv{\cdot}Gy^{-1}{\cdot}cm^{-2}$), CT의 DLP ($201mGy{\cdot}cm$), 유효선량은 0.483 mSv로 산출되었다. 엑스선, 초음파 및 CT에서 정맥내 카테터 조각을 임상적으로 검출하였고, 조각의 묘출 능력에는 CT가 우수하였다. 그러나 엑스선 및 CT는 방사선 피폭을 수반하여 정맥내 카테터 조각의 위치 및 정보를 확인하는 데는 초음파 검사를 추천한다.
