Abstract: According to one embodiment, a medical image diagnostic apparatus includes a storage memory, processing circuitry, and a display. The storage memory stores data of a plurality of FFR distribution maps constituting a time series regarding a coronary artery, and data of a plurality of morphological images corresponding to the time series. The processing circuitry converts the plurality of FFR distribution maps into a plurality of corresponding color maps, respectively. The display displays a plurality of superposed images obtained by superposing the plurality of color maps and the plurality of morphological images respectively corresponding in phase to the plurality of color maps. The display restricts display targets for the plurality of color maps based on the plurality of FFR distribution maps or the plurality of morphological images.

Abstract: A medical information processing apparatus according to an embodiment includes a first analysis unit, a second analysis unit, a determination unit, and a third analysis unit. The first analysis unit executes a first analysis based on a medical image of a subject. The second analysis unit executes a second analysis based on a specimen examination result of the subject. The determination unit determines a matching degree between the result of the first analysis by the first analysis unit and the result of the second analysis by the second analysis unit. The third analysis unit executes a third analysis based on the medical image and the specimen examination result according to analysis conditions based on the determination result of the matching degree by the determination unit, and determines diagnosis support information based on the medical image and the specimen examination result.

Abstract: A medical information processing device of an embodiment includes processing circuitry. The processing circuitry acquires a first attribute factor group which is a plurality of attribute factors relating to a disease of a target patient and which is a plurality of attribute factors at a first timing. The processing circuitry estimates a second attribute factor group which is a plurality of attribute factors at a second timing after the first timing on the basis of the first attribute factor group. The processing circuitry outputs information including the first attribute factor group and the second attribute factor group via an output interface.
