TLDR
Pulmonary hemodynamics is studied in terms of the quasi one-dimensional unsteady nonlinear fluid flow equations which are applied to the 40-odd generations of branched arterial, capillary and venous distensible vessel segments making up the four lobes of the complete lung.About:

Journal ArticleDOI
A global mathematical model of the cerebral circulation in man
TL;DR: A close relationship between cerebral blood flow (CBF) and capillary pressure was obtained and the quasilinear hyperbolic system of equations was numerically solved using the two-step Lax-Wendroff scheme.
Journal ArticleDOI
Negative wave reflections in pulmonary arteries
TL;DR: The pulmonary arterial branching pattern suggests that the early systolic forward-going compression wave (FCW) might be reflected as a backward-going expansion wave (BEW), which is characterized by negative wave reflection tending to facilitate right ventricular ejection; this reflection increases with increasing blood volume and PEEP.

TL;DR: To evaluate the relationship between gadolinium concentration and signal‐to‐noise ratio (SNR) on sensitivity encoding (SENSE) images, and determine the appropriate bolus injection protocol for visualizing pulmonary circulation.

Prognostic value of dynamic MR imaging for non-small-cell lung cancer patients after chemoradiotherapy.
Yoshiharu Ohno,Munenobu Nogami,Takanori Higashino,Daisuke Takenaka,Sumiaki Matsumoto,Hiroto Hatabu,Kazuro Sugimura +6 more
TL;DR: To determine the prognostic value of dynamic MRI for non‐small‐cell lung cancer (NSCLC) patients after chemoradiotherapy, dynamic MRI is used as a standalone test for cancer prognosis.

Dynamic MRI, dynamic multidetector-row computed tomography (MDCT), and coregistered 2-[fluorine-18]-fluoro-2-deoxy-D-glucose-positron emission tomography (FDG-PET)/CT: comparative study of capability for management of pulmonary nodules.
Yoshiharu Ohno,Hisanobu Koyama,Daisuke Takenaka,Munenobu Nogami,Yoshimasa Maniwa,Yoshihiro Nishimura,Chiho Ohbayashi,Kazuro Sugimura +7 more
TL;DR: To compare the nodule management capabilities of dynamic MRI, dynamic multidetector‐row computed tomographic (MDCT) and coregistered positron emission tomography (PET)/CT, three algorithms are compared.

Journal ArticleDOI
Distribution of blood flow in isolated lung; relation to vascular and alveolar pressures.
TL;DR: The left lung from a dog was removed, ventilated with negative pressure, and perfused with venous blood to establish pulmonary arterial, venous, and alveolar pressures that could be varied over a large range.

Hemodynamics of collapsible vessels with tone: the vascular waterfall.
S. Permutt,R. L. Riley +1 more
TL;DR: A theoretical analysis is presented of pressure-flow relationships in arterioles based on the assumption that the presence of active tension produced by smooth muscle contraction causes a critical release of pressure in arteries.

Pulmonary Arterial Pulse Wave Velocity and Impedance in Man
TL;DR: The elasticity of the pulmonary arterial tree appears to be as important as the state of the arterioles and capillaries in determining the energy required for pulsatile pulmonary blood flow.
