1. A similarity determination apparatus that determines a similarity between a first three-dimensional medical image and a second three-dimensional medical image, the similarity determination apparatus comprising at least one processor, wherein the processor is configured to:
classify each pixel of the first medical image into at least one of a plurality of types of findings;
calculate a first feature amount for each finding classified in the first medical image;
derive the similarity between the first medical image and the second medical image on the basis of the first feature amount for each finding calculated in the first medical image and a second feature amount for each finding calculated in the second medical image; and
determine at least one important region including an important finding for deriving the similarity in the second medical image.
