Measurement of Gray and White Matter Atrophy in Dementia with Lewy Bodies Using Diffeomorphic Anatomic Registration through Exponentiated Lie Algebra: A Comparison with Conventional Voxel-Based Morphometry

Autor: Toshiki Yoshikawa, R. Takahashi, Kenichi Shimada, N. Miyamoto, Kazunari Ishii, Shingo Ohkawa, K. Yokoyama, Tatsuya Kakigi

Publikováno v: AJNR Am J Neuroradiol

BACKGROUND AND PURPOSE: DLB is recognized as the second major form of dementia in the elderly. The regional pattern of GM atrophy in DLB highly overlaps that in AD. The aim of this study was to identify the critical pattern of atrophy in DLB by using

Differential Diagnosis of Dementia with Lewy Bodies and Alzheimer Disease Using Combined MR Imaging and Brain Perfusion Single-Photon Emission Tomography

Autor: Kenichi Shimada, N. Miyamoto, H. Goto, Shingo Ohkawa, Takafumi Uemura, Kazunari Ishii, Toshiki Yoshikawa

Publikováno v: AJNR Am J Neuroradiol

BACKGROUND AND PURPOSE: Diagnostic performance by MR imaging or by SPECT alone in discriminating DLB patients from AD patients has been estimated previously. However, the performance of a combination of MR imaging and SPECT has not yet been evaluated

Global Cerebral Hypoperfusion in a Patient With Transient Global Amnesia

Autor: Kotaro Shimizu, Shingo Ohkawa, Toshiki Yoshikawa, Naokazu Miyamoto, Keitaro Sofue, Yumiko Yamane, Kazunari Ishii

Publikováno v: Journal of Computer Assisted Tomography. 32:415-417

We report a 64-year-old male patient with pure transient global amnesia (TGA) who exhibited global cerebral hypoperfusion during an amnesia attack. Initial single photon emission computed tomography (SPECT) performed 3 hours after the onset of the am

Computer-assisted system for diagnosis of Alzheimer disease using data base- independent estimation and fluorodeoxyglucose- positron-emission tomography and 3D-stereotactic surface projection

Autor: Kazunari Ishii, N. Miyamoto, Toshiki Yoshikawa, Takafumi Uemura

Publikováno v: AJNR Am J Neuroradiol

BACKGROUND AND PURPOSE: Recently, voxel-based statistical parametric images have been developed as additional diagnostic tools for AD. However these methods require the generation of a data base of healthy brain images. The purpose of this study was
