Abstract
Purpose: A whole body scan using a radioactive iodine (I-131) for the patients with differentiated thyroid cancer is generally an useful method to detect the remnant thyroid tissue, recurred lesion or metastasis lesion after a surgery. The high dose treatment using the radioactive iodine recently tends to increase, and a hospitalization wait for the treatment has been delayed for several months. In this hospital, the treatable patients per week were increased in number through expanding a water-purifier tank and the examination time also increased as the I-131 whole body scan patients increased. Improvement for this problem, this research reduce the existing examination time and classifying the lesion's exact position intended to by fabricating and utilizing the transmission scan tool and an excellent resolution for whole body imaging. Materials and Methods: After conducting the whole body scan for patients who visited the department from February to July 2008 and received the I-131 whole body scan using the ORBITER Gamma Camera. A rail was installed in the examination table for the transmission scan for show a contour of surface area and then the transmission image was obtained and fused to the whole body scan through fabricating the tool to put a flood phantom of diluted 2 mCi
목적 : 분화된 갑상선암 환자에서 방사성옥소(I-131)를 이용한 전신스캔은 보통 수술 후 잔여 갑상선 조직, 재발된 병변 부위 또는 전이 병소 등을 찾는데 유용한 방법이다. 최근 고선량 방사성동위원소를 이용한 치료는 증가 추세에 있으며, 동위원소 치료를 위한 입원대기는 수개월씩 지연되고 있다. 본원에서는 정화조 설비를 확장하여 주당 치료 가능 인원이 증가되었고 이로 인해 I-131 전신스캔 환자가 늘어나면서 검사시간 또한 증가되었다. 이를 개선하기 위해 본 연구에서는 기존의 검사시간을 단축하면서 병소의 위치를 정확하게 구별할 수 있도록 Transmission scan tool을 제작하여 우수한 분해능을 가진 전신영상을 얻고자 한다. 실험재료 및 방법 : 2008년 2월부터 7월까지 본과를 내원하고 ORBITER Gamma Camera를 이용하여 I-131 전신스캔을 시행하는 환자를 대상으로 하였다. 먼저 전신 스캔을 시행한 후 Transmission scan를 위해 검사 Table에 Rail을 설치하고
