Pulmonary Blood Volume Measured by Dual-Energy Computed Tomography Can Help Distinguish Patients With Pulmonary Hypertension [PDF]
Frontiers in Cardiovascular Medicine, 2022 PurposeTo evaluate the correlation between whole lung enhancement (WLE) and pulmonary blood volume (PBV) obtained through dual energy computed tomography pulmonary angiography (DECTPA) and echocardiography-derived systolic pulmonary arterial pressure ...

Pulmonary blood volume estimation in mice by magnetic particle imaging and magnetic resonance imaging [PDF]
Scientific Reports, 2021 This methodical work describes the measurement and calculation of pulmonary blood volume in mice based on two imaging techniques namely by using magnetic particle imaging (MPI) and cardiac magnetic resonance imaging (MRI). Besides its feasibility aspects

Effect of nitroglycerin on splanchnic and pulmonary blood volume. [PDF]
J Nucl Cardiol, 2022 Sublingual nitroglycerin (SL NTG) is useful for treating acute decompensated heart failure, possibly by increasing splanchnic capacitance and reducing left ventricular (LV) preload. We evaluated a radionuclide method to study these effects, initially in subjects without heart failure.Red blood cells were labelled by an in vitro method.

Pulmonary blood volume measured by cardiovascular magnetic resonance: influence of pulmonary transit time methods and left atrial volume [PDF]
Journal of Cardiovascular Magnetic Resonance, 2021 Background Increased pulmonary blood volume (PBV) is a measure of congestion and is associated with an increased risk of cardiovascular events. PBV can be quantified using cardiovascular magnetic resonance (CMR) imaging as the product of cardiac output ...

Anthropometry, sex, and age at diagnosis affect pulmonary blood volume quantification from computed tomography pulmonary angiography in pulmonary hypertension assessment [PDF]
Frontiers in Cardiovascular MedicineIntroductionThe influence of anthropometrics, sex, and age at diagnosis on artificial intelligence (AI)–derived pulmonary blood volumes (PBV) from computed tomography pulmonary angiography (CTPA) remains poorly characterized.

Contrast echocardiography for pulmonary blood volume quantification
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2004 Pulmonary blood volume quantification is important both for diagnosis and for monitoring of the circulatory system. It requires employment of transpulmonary indicator dilution techniques, which are very invasive due to the need for double catheterization. This paper presents a new minimally invasive technique for blood volume quantification.

Determinants of pulmonary blood volume [PDF]
Journal of Clinical Investigation, 1970 Pulmonary blood volume was determined by the radiocardiographic technique in 49 patients coming to cardiac catheterization. Since this method has not been directly compared with the more commonly used double injection of dye. 25 comparisons were carried out in 13 patients of the series.
