Abstract
Purpose : Because of the rapid physical decay of the short half-lived radionuclide, counting of event for image is very limited. In this reason, long scan duration is applied for more accurate quantitative analysis in the relatively low sensitive examination. The aim of this study was to evaluate the difference according to scan duration and investigate the resonable scan duration using the radionuclide of 11C and 18F in PET scan. Materials and Methods : 1994-NEMA Phantom was filled with 11C of
단 반감기 핵종을 이용한 PET검사는 방사성동위원소의 빠른 물리적 붕괴로 인하여 영상 획득을 위한 계수검출이 제한적이다. 이러한 이유로 비교적 낮은 감도의 검사에서는 보다 정확한 정량적 평가를 위하여 긴 시간동안 영상 획득을 적용하기도 한다. 본 연구에서는
