Abstract
Purpose: Standardized uptake value (SUV) is a simple semi-quantitative method that can measure the ratio of the tissue radioactivity between the tumor and normal. SUV is commonly used in PET/CT, however, SUV is affected by various factor. The purpose of this study was to evaluate the impact of the residual activity on SUV depending on the location of catheter insertion device post injection. Materials and Methods: NEMA IEC Body Phantom was imaged using a Discovery 600 PET scanner. In 22 mm diameter sphere, the different activity of
PET/CT 영상에서 표준섭취계수(Standardized uptake value, SUV)는 간단한 반정량적인 방법으로 정상 조직과 종양 조직의 섭취 비를 측정하여 임상에서 육안적인 평가와 함께 유용하게 사용되고 있지만 많은 변수들로 인해 SUV에 영향을 주게 된다. 그 중 혈관 삽입기구나, 주사 부위의 잔여 방사능과 그 위치에 따라서 영향을 평가해 보고자 한다. GE Discovery 600 (GE Healthcare, MI, USA)과 NEMA IEC Body Phantom을 사용하였다.
