  • Analysis apparatus and analysis program
    Patent number: 11534119
    Abstract: An analysis apparatus according to an embodiment includes an extraction unit, a calculation unit, and an evaluation unit. The extraction unit extracts a detection value in a tumor region, a blood region, and a muscle region from a nuclear medicine image of a subject administered with a drug containing a radiolabeled anticancer drug that works by accumulating in a tumor. The calculation unit calculates a first comparison value that is a comparison result between the detection value in the blood region and the detection value in the tumor region, and a second comparison value that is a comparison result between the detection value in the muscle region and the detection value in the tumor region. The evaluation unit evaluates an accumulation of the drug in the tumor, based on the first comparison value and the second comparison value calculated by the calculation unit.
