An MRI apparatus comprising: a scanner comprising a static magnetic field magnet configured to generate a static magnetic field, a gradient coil configured to generate a gradient magnetic field, and a WB "Whole Body" coil configured to apply an RF pulse to an object, the scanner being configured to image a human brain; and processing circuitry configured to cause the scanner to image, under a first imaging method, a tissue including a perfusion route of a body fluid that removes waste products of the human brain, wherein the first imaging method is an imaging method of depicting the body fluid hyperintensely, wherein the body fluid is dural lymphatic fluid or cerebrospinal fluid presumed to flow out through a wall of a superior sagittal sinus "SSS", generate an anatomical image of the tissue from first data acquired by imaging under the first imaging method, wherein the anatomical image is an image that depicts a region including a subarachnoid space "SAS", a superior sagittal sinus "SSS", a wall of the superior sagittal sinus, and a parasagittal dura "PSD", cause the scanner to image perfusion behavior of the body fluid in real time under a second imaging method using non-contrast perfusion imaging, generate a perfusion image indicating the perfusion behavior of the body fluid from second data acquired by imaging under the second imaging method, and generate a fused image by combining the anatomical image and the perfusion image. a scanner comprising a static magnetic field magnet configured to generate a static magnetic field, a gradient coil configured to generate a gradient magnetic field, and a WB "Whole Body" coil configured to apply an RF pulse to an object, the scanner being configured to image a human brain; and processing circuitry configured to cause the scanner to image, under a first imaging method, a tissue including a perfusion route of a body fluid that removes waste products of the human brain, wherein the first imaging method is an imaging method of depicting the body fluid hyperintensely, wherein the body fluid is dural lymphatic fluid or cerebrospinal fluid presumed to flow out through a wall of a superior sagittal sinus "SSS", generate an anatomical image of the tissue from first data acquired by imaging under the first imaging method, wherein the anatomical image is an image that depicts a region including a subarachnoid space "SAS", a superior sagittal sinus "SSS", a wall of the superior sagittal sinus, and a parasagittal dura "PSD", cause the scanner to image perfusion behavior of the body fluid in real time under a second imaging method using non-contrast perfusion imaging, generate a perfusion image indicating the perfusion behavior of the body fluid from second data acquired by imaging under the second imaging method, and generate a fused image by combining the anatomical image and the perfusion image. cause the scanner to image, under a first imaging method, a tissue including a perfusion route of a body fluid that removes waste products of the human brain, wherein the first imaging method is an imaging method of depicting the body fluid hyperintensely, wherein the body fluid is dural lymphatic fluid or cerebrospinal fluid presumed to flow out through a wall of a superior sagittal sinus "SSS", generate an anatomical image of the tissue from first data acquired by imaging under the first imaging method, wherein the anatomical image is an image that depicts a region including a subarachnoid space "SAS", a superior sagittal sinus "SSS", a wall of the superior sagittal sinus, and a parasagittal dura "PSD", cause the scanner to image perfusion behavior of the body fluid in real time under a second imaging method using non-contrast perfusion imaging, generate a perfusion image indicating the perfusion behavior of the body fluid from second data acquired by imaging under the second imaging method, and generate a fused image by combining the anatomical image and the perfusion image.
