Quantitative assessment of regional pulmonary perfusion in the entire lung using three‐dimensional ultrafast dynamic contrast‐enhanced magnetic resonance imaging: Preliminary experience in 40 subjects
Yoshiharu Ohno,Hiroto Hatabu,Kenya Murase,Takanori Higashino,Hideaki Kawamitsu,Hirokazu Watanabe,Daisuke Takenaka,Masahiko Fujii,Kazuro Sugimura +8 more
TL;DR: To assess regional differences in quantitative pulmonary perfusion parameters, i.e., pulmonary blood flow, mean transit time (MTT), and pulmonary blood volume (PBV) in the entire lung on a pixel‐by‐pixel basis in normal volunteers and pulmonary hypertension patients, a large number of patients are diagnosed with pulmonary hypertension.

Efficient method for calculating kinetic parameters using T1-weighted dynamic contrast-enhanced magnetic resonance imaging.
TL;DR: The usefulness of this method was investigated by means of computer simulations, in comparison with the nonlinear least‐squares (NLSQ) method, and it was found that it estimated the above parameters faster than the NLSQ method by a factor of approximately 6, and estimated them more accurately at a signal‐to‐noise ratio (SNR) of < ∼10.

Relationship between variations in the circle of willis and flow rates in internal carotid and basilar arteries determined by means of magnetic resonance imaging with semiautomated lumen segmentation : Reference data from 125 healthy volunteers
TL;DR: Variations in the circle of Willis correlate significantly with relative contributions by the flow rates of the bilateral internal carotid and basilar arteries of normal volunteers.

Primary pulmonary hypertension: 3D dynamic perfusion MRI for quantitative analysis of regional pulmonary perfusion.
Yoshiharu Ohno,Hiroto Hatabu,Kenya Murase,Takanori Higashino,Munenobu Nogami,Takeshi Yoshikawa,Kazuro Sugimura +6 more
TL;DR: Three-dimensional dynamic contrast-enhanced MRI has potential for assessment of disease severity as indicated by PVR and MPAP in patients with PPH.

Comparison of Regional Brain Volume and Glucose Metabolism Between Patients with Mild Dementia with Lewy Bodies and Those with Mild Alzheimer's Disease
Kazunari Ishii,Tsutomu Soma,Atsushi K. Kono,Keitaro Sofue,Naokazu Miyamoto,Toshiki Yoshikawa,Etsuro Mori,Kenya Murase +7 more
TL;DR: Comparison of very mild DLB and AD revealed different morphologic and metabolic changes occurring in the medial temporal lobes and the occipital lobe, demonstrating characteristic pathophysiologic differences between these 2 diseases.
