MIRD (Medical Internal Radiation Dose) Method: Basics and Recent Efforts

Abstract

The MIRD method is a method for evaluating internal radiation doses from radiopharmaceuticals proposed by the MIRD Committee of the Society of Nuclear Medicine and Molecular Imaging (SNMMI). The basic concept of the MIRD method proposed more than half a century ago has not changed significantly to this day, but it has evolved into a highly accurate method with the development of mathematical (or computational) phantoms and Monte Carlo calculations. In addition, the calculation software recently distributed by the MIRD Committee includes some recent efforts. This report outlines the basics of the MIRD method and recent efforts of the MIRD committee.
