Abstract

The aim of this study was to develop and distribute a dedicated program that can easily calculate the effective dose of a patient undergoing nuclear medicine examinations, and assist in the study of dose of nuclear medicine examinations and information disclosure. The program produced a database of the effective dose per unit activity administered (mSv/MBq) of the radiopharmaceuticals listed in ICRP 80, 106 Report and the fourth addendum, was designed through Microsoft Visual Basic (In Excel) to take the effect of 5 different (Area, Clark, Solomon(=Fried), Webster, Young) of pediatric dose calculation methods and 7 different body surface area calculation methods. The program calculates the effective dose (mSv) when the age, radionuclide, substance, and amount injected in the human body is inputted. In pediatric cases, when the age is entered, the pediatric method is activated and the pediatric method to be applied can be selected. When the BSA (Body Surface Area) formula is selected in the pediatric calculation method, a selection window for selecting the body surface area calculation method is activated. When the adult dose is input, the infant dose and the effective dose (mSv) are calculated automatically. The patient effective dose calculation program of the nuclear medicine examinations produced in this study is meaningful as a tool for calculating the internal exposure dose of the human body that is most likely to be obtained in nuclear medicine examinations, even though it is not the actual measurement dose. In the future, to increase the utilization of the program, it will be produced as an application that can be used in mobile devices, so that the public can access it easily.

본 연구의 목적은 핵의학검사를 하는 수검자(환자)의 유효선량(mSv)을 손쉽게 산출할 수 있는 전용 프로그램을 제작 보급하여 핵의학검사의 피폭선량 연구와 선량정보 공개를 위해 조력하고자 한다. 프로그램은 ICRP 80, 106 Report와 추록4에 수록되어 있는 방사성의약품의 방사능당 유효선량(mSv/MBq)을 Database로 만든 다음 5가지(Area, Clark, Solomon(Fried), Webster, Young) 소아주입량 산출법과 7가지 체표면적 산출법이 적용되도록 Microsoft의 Visual Basic(In Excel)으로 제작하였다. 프로그램은 수검자의 연령, 방사성핵종, 표지화합물, 그리고 인체주입량을 입력하면 유효선량(mSv)이 산출된다. 소아의 경우 연령 입력 시 소아산출법이 활성화 되며 적용할 소아산출법을 선택하면 된다. 그리고 소아산출법 중 Area법을 선택하는 경우 체표면적산출법을 고르는 선택창이 활성화 된다. 그런 다음 성인의 주입량을 입력하면 소아의 주입량과 유효선량(mSv)이 자동으로 산출된다. 본 연구에서 제작한 핵의학검사의 환자 유효선량 계산 프로그램은 실제 계측선량이 아니지만 핵의학 검사 시 받게 되는 인체의 내부피폭선량을 가장 근접하게 산출할 수 있는 도구로서 의미가 있다. 향후 프로그램의 활용도를 높이기 위해 모바일기기에서 사용할 수 있는 애플리케이션으로 제작하여 일반인도 쉽게 접근할 수 있도록 할 것이다.
