This PET-MRI device (100) is provided with: a mount including a static magnetic field magnet (1), a gradient magnetic field coil (3), and a high-frequency coil (5); PET detectors (13, 13a, 13b, 13c); and movement mechanisms (20, 20a, 20b, 20c). The static magnetic field magnet (1) produces a static magnet field within a substantially cylindrical bore. The gradient magnetic field coil (3) is arranged on an inner peripheral side of the static magnetic field magnet (1), and applies a gradient magnetic field to a subject arranged within the bore. The high-frequency coil (5) is arranged on an inner peripheral side of the gradient magnetic field coil (3), and applies a high-frequency magnetic field to the subject. The PET detectors (13, 13a, 13b, 13c) detect gamma rays emitted from positron-emitting radionuclides administered to the subject. The movement mechanisms (20, 20a, 20b, 20c) move the PET detectors (13, 13a, 13b, 13c) along the axial direction of the bore within the mount. |
