HARDNESS DISTRIBUTION IMAGE ACQUISITION METHOD USING MAGNETIC RESONANCE IMAGING DEVICE AND MAGNETIC RESONANCE IMAGING DEVICE

摘要

It is possible to easily and with a preferable S/N ratio, image hardness/softness (viscosity/elasticity) of a biological tissue and its dynamic change by quasi-real time measurement which reduces the time required from an RF pulse excitation until an NMR signal measurement without causing a load to an inclined magnetic field. For this, a plurality of images are acquired in quasi-real time while applying pressure and vibration from an examinee body surface. While correlating local areas between adjacent images, a displacement amount of the local area or distortion distribution or their pseudo-color display is obtained, thereby displaying an image representing a sclerosing degree of the tissue.
