Pulmonary Blood Volume and Pulmonary Capillary Blood Volume in Valvular Heart Disease [PDF]

Circulation, 1967
Measurements of pulmonary blood volume (PBV) and pulmonary capillary blood volume (V c ) and hemodynamic studies were made in a series of 106 patients with valvular heart disease (62 with predominant mitral lesions and 44 with predominant aortic lesions).

Quantitative CT measures of pulmonary vascular volume distribution in pulmonary hypertension associated with COPD: Association with clinical characteristics and outcomes

Pulmonary Circulation, 2023
To determine whether quantitative computed tomography (qCT)‐derived metrics of pulmonary vascular volume distribution could distinguish chronic obstructive pulmonary disease (COPD) subjects with associated pulmonary hypertension (PH) from those without ...

Effect of Frusemide on Pulmonary Blood Volume [PDF]

BMJ, 1969
Intracardiac frusemide given to seven patients recovering from high-altitude pulmonary oedema caused a significant reduction in the pulmonary blood volume before the onset of diuresis. This supports the suggestion that the mobilization of fluid from the pulmonary circuit is responsible for the relief of symptoms in some patients with pulmonary oedema ...

Computed tomography-based imaging biomarker identifies coal workers’ pneumoconiosis

Frontiers in Physiology, 2023
Rationale: The increase in the incidence and the diagnostic limitations of pneumoconiosis have emerged as a public health concern. This study aimed to conduct a computed tomography (CT)- based quantitative analysis to understand differences in imaging ...

Pulmonary artery blood flow dynamics in chronic thromboembolic pulmonary hypertension

Scientific Reports, 2023
Chronic thromboembolic pulmonary hypertension is caused by incomplete resolution and organization of thrombi. Blood flow dynamics are involved in thrombus formation; however, only a few studies have reported on pulmonary artery blood flow dynamics in ...

Perioperative CTEPH patient monitoring with 2D phase-contrast MRI reflects clinical, cardiac and pulmonary perfusion changes after pulmonary endarterectomy

PLoS ONE, 2020
Magnetic resonance imaging (MRI) is an emerging tool for diagnosis and treatment monitoring of chronic thromboembolic pulmonary hypertension (CTEPH).

Pulmonary intravascular blood volume changes through the cardiac cycle in healthy volunteers studied by cardiovascular magnetic resonance measurements of arterial and venous flow

Journal of Cardiovascular Magnetic Resonance, 2009
Background This study aims to present a novel method for using cardiovascular magnetic resonance (CMR) to non-invasively quantify the variation in pulmonary blood volume throughout the cardiac cycle in humans.

Severe pulmonary hypertension associated with lung disease is characterised by a loss of small pulmonary vessels on quantitative computed tomography

ERJ Open Research, 2022
Background Pulmonary hypertension (PH) in patients with chronic lung disease (CLD) predicts reduced functional status, clinical worsening and increased mortality, with patients with severe PH-CLD (≥35 mmHg) having a significantly worse prognosis than ...

Supine, prone, right and left gravitational effects on human pulmonary circulation

Journal of Cardiovascular Magnetic Resonance, 2019
Background Body position can be optimized for pulmonary ventilation/perfusion matching during surgery and intensive care. However, positional effects upon distribution of pulmonary blood flow and vascular distensibility measured as the pulmonary blood ...
