Abstract
Purpose: Recently, South Korea has seen a rapidly increased incidence of both breast and thyroid cancers. As a result, the I-131 scan and lymphoscintigraphy have been performed more frequently. Although this type of diagnostic imaging is prominent in that visualizes pathological conditions, which is similar to previous nuclear diagnostic imaging techniques, there is not much anatomical information obtained. Accordingly, it has been used in different ways to help find anatomical locations by transmission scan, however the results were unsatisfactory. Therefore, this study aims to realize an imaging technique which shows more anatomical information through the fusion of gamma and realistic imaging. Materials and Methods: We analyzed the data from patients who were examined by the lymphoscintigraphy and I-131 additional scan by Symbia Gamma camera (SIEMENS) in the nuclear medicine department of the National Cancer Center from April to July of 2009. First, we scanned the same location in patients by using a miniature camera (R-2000) in hyVISION. Afterwards, we scanned by gamma camera. The data we obtained was evaluated based on the scanning that measures an agreement of gamma and realistic imaging by the Gamma Ray Tool fusion program. Results: The amount of radiation technicians and patients were exposed was generated during the production process of flood source and applied transmission scan. During this time, the radiation exposure dose of technicians was an average of 14.1743
현재 우리나라 암발생률을 보면 유방암과 갑상샘암이 매년 빠르게 증가하고 있는 추세이다. 따라서 I-131 scan과 전초림프절 검사인 lymphoscintigraphy가 많이 시행되고 있다. 그러나 이러한 검사는 전통적인 핵의학 영상 검사들과 마찬가지로 병리생태를 영상화하는 데에는 탁월하나 해부학적 정보는 많지 않다. 따라서 트랜스미션 스캔을 실시하여 해부학적 위치를 찾는 데 도움을 주는 등 여러 방법을 사용하고 있으나 만족스럽지 못하다. 이에 착안하여 감마실사영상의 fusion으로 좀 더 해부학적 정보가 많은 영상을 구현하고자 한다. 2009년 4월부터 7월까지 본과를 내원하고 SIEMENS사의 Symbia Gamma Camera를 이용하여 lymphoscintigraphy를 시행한 환자와 I-131 추가 검사를 시행한 환자를 대상으로 하였다. 먼저 감마카메라로 촬영한 후 촬영실 천정에 설치한 hyVISION사의 소형카메라(R-2000)로 동일 위치를 촬영하여 감마영상과 소형카메라의 실사영상을 자체개발한 Gamma Ray Tool Fusion 프로그램을 이용하여 fusion하여 일치도를 평가 하였으며, 환자 및 술자의 피폭선량을 평가하였다. 술자와 환자의 피폭선량은 트랜스미션 스캔을 적용하기 위한 플러드 선원의 제작과정과 실제 트랜스미션 스캔이 적용될 때 방사선피폭이 발생되며 술자의 방사선피폭은 평균 14.1743
