Ishimatsu K, Kikuchi K, Moe O, Oshio K, Ishigami K, Takahashi M
Magn Reson Med Sci
. 2024 Dec;
PMID: 39631855
Purpose: To compare diagnostic reliability between an intravoxel incoherent motion (IVIM) imaging and an arterial spin labeling (ASL) in assessment of renal blood flow in rodents. Methods: We first evaluated...

Koizumi T, Shimizu S, Akiba C, Kakizoe H, Bandai H, Sato K, et al.
Magn Reson Med Sci
. 2024 Sep;
PMID: 39322568
Purpose: T values are hypothesized to be reduced where protein accumulates in the cerebrospinal fluid (CSF). We aimed to verify the accuracy of Carr-Purcell-Meiboom-Gil (CPMG) pulses and non-negative least squares...

Vucevic D, Malis V, Bae W, Ota H, Oshio K, McDonald M, et al.
Bioengineering (Basel)
. 2024 Jul;
11(7).
PMID: 39061790
Intrinsic cerebrospinal fluid (CSF) dynamics in the brain have been extensively studied, particularly the egress sites of tagged intrinsic CSF in the meninges. Although spinal CSF recirculates within the central...

Magn Reson Med Sci
. 2021 Oct;
22(1):137-141.
PMID: 34645739
Although the glymphatic system hypothesis is highly popular, it also lacks certain details. In this paper, an attempt was made to present a more clearly defined hypothesis, which is consistent...

Magn Reson Med Sci
. 2020 Feb;
20(1):34-39.
PMID: 32074590
Purpose: Although there is no lymphatic system in the central nervous system (CNS), there seems to be a mechanism to remove macro molecules from the brain. Cerebrospinal fluid (CSF) and...

Magn Reson Med
. 2017 May;
79(1):383-393.
PMID: 28480603
Purpose: To develop a high-speed T mapping protocol that is capable of accurately measuring T relaxation time constants from a single-shot acquisition. Theory: A new echo-split single-shot gradient-spin-echo (GRASE) pulse...

. 2015 Dec;
15(2):237-45.
PMID: 26701694
Purpose: To determine the appropriateness of statistical models using the truncated Gaussian distribution and gamma distribution for diffusion signal decay, and to assess the correlation between the parameters obtained from...

PMID: 25228852
Lung parenchyma is challenging to image with proton MRI. The large air space results in ~l/5th as many signal-generating protons compared to other organs. Air/tissue magnetic susceptibility differences lead to...
