MAGNETIC RESONANCE IMAGING DEVICE AND IMAGE CREATING METHOD

WIPO Patent Application WO/2016/167047

A1

A group of images necessary for evaluating the hemodynamics of a predetermined site is obtained only from a plurality of types of image capturing that uses an MRI device and does not use a contrast medium, without using a radioactive isotope (such as 15O) or an MRI contrast medium (such as Gd). For example, when the site is the brain, ASL-PWI image capturing, QSM image capturing, and IVIM image capturing are performed, and from the results thereof, a CBF image, an OEF image, a CBV image, a CMRO2 image, and an MTT image necessary for evaluating the hemodynamics of the brain are obtained. Thus, images (bloodstream parameters) necessary for evaluating the hemodynamics of a predetermined site are obtained only by a minimally invasive examination.
