Abstract: An information processing device includes processing circuitry. The processing circuitry acquires a motion history of a patient who represents themselves as an avatar and gets a check-up at a clinic in a metaverse. The processing circuitry determines a specific motion for estimating a state of the patient by analyzing the motion history. The processing circuitry outputs information based on the specific motion via an output interface.

Abstract: A medical image-processing apparatus according to an embodiment includes processing circuitry. The processing circuitry acquires a first medical image captured at first timing, and a second medical image in which an identical position to the first medical image is captured at second timing, which is different from the first timing, identifies a change region to be a logical OR of a first region included in the first medical image and a second region that corresponds to the first region and is included in the second medical image when the first medical image and the second medical image are overlaid on each other in an aligned manner, and calculates a degree of change of the change region between the first timing and the second timing based on the first region and the second region that form the change region.

Abstract: A magnetic resonance imaging apparatus includes sequence controlling circuitry configured: to obtain, during a time period after excitation of a first nuclide in a hyperpolarized state but no later than before obtainment of a first magnetic resonance signal from the first nuclide, a second magnetic resonance signal from a second nuclide that is different from the first nuclide and is in a non-hyperpolarized state, by exciting the second nuclide; and to control each of gradient magnetic field waveforms so as to cause both a first sum indicating a sum of application amounts of a gradient magnetic field related to the excitation of the second nuclide and a second sum indicating a sum of application amounts of a gradient magnetic field related to the obtainment of the second magnetic resonance signal to be close to zero, no later than before the obtainment of the first magnetic resonance signal.
