| Outline of Final Research Achievements |
The phase images, including susceptibility-weighted imaging (SWI), may demonstrate excellent image contrast and reveal anatomical structures that are not visible on conventional MR images. A new phase-weighted MR imaging technique, termed “phase difference enhanced imaging” (PADRE), has been developed in Kumamoto University, in which the phase difference between the target and surrounding tissue was selected in order to enhance the contrast of the target tissue. Choosing the appropriate phase differences allows the variation in tissue contrast using single MR data. We applied this PADRE technique on 3-T MRI to healthy controls and AD patients. These studies demonstrated the possibility of obtaining in vivo radiologic evidence of cerebral amyloid deposition using a routinely available 3-T MRI system.
