Ito K, Hamasaki N, Shirato T, Doryo K, Ozaki Y
Nihon Hoshasen Gijutsu Gakkai Zasshi . 2024 Dec; 81(2). PMID: 39675986
Purpose: The aim of this study was to investigate imaging conditions that allow for the rapid acquisition of mask images used in the subtraction method, one of the depiction improvement...

Murata S, Hagiwara A, Fujita S, Haruyama T, Kato S, Andica C, et al.
Magn Reson Imaging . 2021 Jan; 78:90-97. PMID: 33444595
Introduction: Recently, three-dimensional (3D) quantitative synthetic magnetic resonance imaging (MRI), which quantifies tissue properties and creates multiple contrast-weighted images, has been enabled by 3D-quantification using an interleaved Look-Locker acquisition sequence...

Murata S, Tachibana Y, Murata K, Kamagata K, Hori M, Andica C, et al.
Jpn J Radiol . 2019 Jun; 37(8):579-589. PMID: 31230186
Purpose: Image contrast differs between conventional multislice turbo spin echo (conventional TSE) and multiband turbo spin echo (SMS-TSE). Difference in time interval between excitations for adjacent slices (SETI) might cause...

Sci Rep . 2018 Mar; 8(1):5213. PMID: 29581458
Mapping of MR fiber g-ratio, which is the ratio of the diameter of the axon to the diameter of the neuronal fiber, is introduced in this article. We investigated the...

Andica C, Hori M, Kamiya K, Koshino S, Hagiwara A, Kamagata K, et al.
Magn Reson Med Sci . 2017 Nov; 17(3):269-272. PMID: 29129844
We report two cases of pathologically proven intracranial epidermoid cysts. Both cases were scanned with diffusion-weighted imaging using pulsed gradient spin-echo (PGSE) and oscillating gradient spin-echo (OGSE; 50 Hz) prototype...

Takamura T, Hori M, Kamagata K, Kumamaru K, Irie R, Hagiwara A, et al.
Jpn J Radiol . 2017 Nov; 36(1):40-50. PMID: 29086345
Purpose: To assess the influence of high temporal resolution on the perfusion measurements and image quality of perfusion maps, by applying simultaneous-multi-slice acquisition (SMS) dynamic susceptibility contrast-enhanced (DSC) magnetic resonance...

Acta Radiol Open . 2016 Mar; 5(2):2058460115626757. PMID: 26962461
Background: Synthetic magnetic resonance imaging (MRI), a technique that enables creation of various contrast-weighted images from a single MRI quantification scan, is a useful clinical tool. However, there are currently...

Magn Reson Imaging . 2014 Apr; 32(6):625-9. PMID: 24726649
Introduction: Diffusion tensor imaging (DTI) reveals white matter pathology in patients with multiple sclerosis (MS). A recent non-Gaussian diffusion imaging technique, q-space imaging (QSI), may provide several advantages over conventional...
