MIRD法は，米国核医学会のMIRD委員会により提案された，放射性医薬品の内部被ばく線量評価の方法である。半世紀以上前に提案されたMIRD法の基本概念は，現在でも大きく変わっていないが，数学ファントムやモンテカルロ計算の発達とともに，高精度な方法へと進化した。また，最近，MIRD委員会が配布した計算ソフトには，新しい取り組みが幾つか含まれている。本報告では，基礎と最近の取り組みを概説する。
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.
Key words: dosimetry; MIRDcalc; phantom; blood source; detriment-weighted dose
