PRESSURE SENSOR AND PRESSURE SENSING METHOD UTILIZING MRI, COMPUTER SYSTEM AND COMPUTER-READABLE MEDIUM

Japanese Patent JP2012024217

A

To noninvasively evaluate a pressure change inside a skull with a caudate nucleus or a putamen inside a brain as a sensing head.

This pressure sensor utilizing MRI (magnetic resonance imaging) includes: an acquisition means acquiring diffusion anisotropic information of water in the caudate nucleus and/or the putamen of the brain from a diffusion tensor magnetic resonance signal including position information by use of an MRI apparatus 1 and an arithmetic processor 2; a specification means specifying a diffusion parameter according with an FA (fractional anisotropy) value of 0.18-0.45 decided that pressure is received by utilization of the diffusion anisotropic information as pressure change information including the position information; an imaging means imaging the pressure change information by use of the position information; and a display means superposing the pressure change information on an image imaged with the caudate nucleus and/or the putamen of the brain by use of the position information and displaying it. By using the caudate nucleus and/or the putamen that is a three-dimensional structure as the sensing head, the pressure change of the brain is noninvasively measured.
