Pulmonary artery distensibility was studied with spin-echo magnetic resonance imaging in
20 normal subjects of variable age and in four patients with pulmonary arterial hypertension …

Axial, dual spin-echo magnetic resonance (MR) images, taken at the level of the pulmonary
arteries and gated to the cardiac cycle, were qualitatively and quantitatively evaluated in …

Magnetic resonance imaging (MRI) was used to examine the right ventricle and pulmonary
arteries in 17 patients with pulmonary artery (PA) hypertension documented by cardiac …

The use of magnetic resonance (MR) images for estimating mean pulmonary artery pressure
(PAP) was tested by comparing main pulmonary artery (MPA) and middescending thoracic …

A study was performed to determine the value of MR imaging in detecting pulmonary artery
hypertension and in determining pulmonary artery pressure semiquantitatively. MR studies …

Velocity-encoded cine magnetic resonance (MR) imaging provides two-dimensional velocity
maps of a cross-sectional area of a vessel. Pulmonary flow and flow patterns in the main …

The aims of this study were first to analyze pulmonary flow differences between patients with
primary pulmonary hypertension (PPH) and volunteers, and second to determine whether …

We used magnetic resonance imaging with cine velocity mapping to study the anatomy of
pulmonary bifurcation and to measure volume blood flow, pulsatility of flow and arterial wall …

The pulmonary arteries dilate in response to many factors, principally increased pressure
and flow. In patients who have pulmonary arterial hypertension but no increase in flow, we …

Cine gradient-recalled magnetic resonance (MR) imaging, which has flow sensitivity and
high temporal resolution, may potentially yield both morphologic and dynamic flow-related …
