1. An image analysis apparatus, comprising a hardware processor that:
analyzes at least one dynamic radiograph formed from a plurality of two-dimensional images acquired by radiographing dynamics of a subject including a trachea and/or a bronchus to measure feature amounts representing a stenotic state of the trachea and/or the bronchus, the feature amounts including a diameter and concentration of the trachea and/or bronchus; and
estimates the stenotic state based on a result of the measurement of at least one of the diameter and the concentration of the trachea and/or the bronchus and identifies an individual specific disorder by selecting the individual specific disorder from a plurality of specific disorders of the trachea and/or the bronchus based on a result of the measurement of both of the diameter and the concentration of the trachea and/or the bronchus.
