Okuchi S, Fushimi Y, Sakata A, Otani S, Nakajima S, Maki T, et al.
Sci Rep
. 2025 Feb;
15(1):6512.
PMID: 39987155
The efficacy of 2D turbo gradient- and spin-echo diffusion-weighted imaging with non-Cartesian BLADE trajectory (TGSE-BLADE DWI) has not been well studied for acute stroke due to its long acquisition time....

Jpn J Radiol
. 2025 Jan;
PMID: 39794660
Purpose: Magnetization prepared rapid gradient echo (MPRAGE) is a useful three-dimensional (3D) T1-weighted sequence, but is not a priority in routine brain examinations. We hypothesized that converting 3D MRI localizer...

Otani S, Fushimi Y, Okuchi S, Sakata A, Yamamoto T, Nakajima S, et al.
Jpn J Radiol
. 2024 Dec;
PMID: 39730930
Purpose: To compare quantitative values and image quality between single-shot echo-planar imaging (SS-EPI) diffusion-weighted imaging (DWI) and two-dimensional turbo gradient- and spin-echo DWI with non-Cartesian BLADE trajectory (TGSE-BLADE DWI) in...

Sakurama A, Fushimi Y, Nakajima S, Sakata A, Okuchi S, Yamamoto T, et al.
Jpn J Radiol
. 2024 Oct;
43(3):379-388.
PMID: 39467931
Purpose: We compared quantitative susceptibility mapping (QSM) with wave-CAIPI 9 × (QSM_WC9 ×) with reference standard QSM with GRAPPA 2 × (QSM_G2 ×) in two MR scanners. We also compared...

Wang Y, Fushimi Y, Nakajima S, Sakata A, Okuchi S, Otani S, et al.
Acad Radiol
. 2024 Sep;
32(1):391-399.
PMID: 39227216
Rationale And Objectives: Gadolinium deposition in the dentate nucleus (DN) has been evaluated by T1-weighted imaging (T1WI) and T1 (R1) mapping, but not MR fingerprinting (MRF). This study investigated associations...

Neuroradiology
. 2024 Apr;
66(6):973-981.
PMID: 38653782
Purpose: The rarity of IDH2 mutations in supratentorial gliomas has led to gaps in understanding their radiological characteristics, potentially resulting in misdiagnosis based solely on negative IDH1 immunohistochemical staining. We...

Ito S, Okuchi S, Fushimi Y, Otani S, Wicaksono K, Sakata A, et al.
Eur Radiol Exp
. 2024 Mar;
8(1):28.
PMID: 38448783
Background: To evaluate the clinical usefulness of thin-slice echo-planar imaging (EPI)-based diffusion-weighted imaging (DWI) with an on-console distortion correction technique, termed reverse encoding distortion correction DWI (RDC-DWI), in patients with...

Numamoto H, Fujimoto K, Miyake K, Fushimi Y, Okuchi S, Imai R, et al.
Magn Reson Med Sci
. 2023 Nov;
24(1):66-77.
PMID: 37952942
Purpose: To compare image distortion and reproducibility of quantitative values between reverse encoding distortion correction (RDC) diffusion-weighted imaging (DWI) and conventional DWI techniques in a phantom study and in healthy...

Eur Radiol
. 2023 Oct;
34(4):2183-2194.
PMID: 37798407
Objective: To investigate the relationship of followings for patients with moyamoya disease (MMD): arterial wall enhancement on vessel wall MRI (VW-MRI), cross-sectional area (CSA), time-of-flight MR angiography (MRA), age, locations...
