Magnetic resonance quantification of regional blood flow and oxygen delivery to the brain, gut, kidneys, and lower extremities in adolescents with a Fontan circulation compared to biventricular controls. [PDF]

J Cardiovasc Magn Reson
: Background: Accumulation of progressive extracardiac disease is nearly universal for patients with single ventricle heart disease palliated to a Fontan circulation; however, etiologies are poorly understood.

Sex Differences in Regional Cerebral Blood Flow

Journal of Cerebral Blood Flow and Metabolism, 1988
Regional cerebral blood flow was measured by the 133-xenon inhalation method during resting in 38 healthy men and 38 healthy women matched pairwise for age in the range 18-72 years. The results showed 11% higher global flow level in the women in all ages.

Pancreatic regional blood flow links the endocrine and exocrine diseases. [PDF]

J Clin Invest, 2023
An increasing number of studies have demonstrated that disease states of the endocrine or exocrine pancreas aggravate one another, which implies bidirectional blood flow between islets and exocrine cells.

Regional myocardial strain analysis via 2D speckle tracking echocardiography: validation with sonomicrometry and correlation with regional blood flow in the presence of graded coronary stenoses and dobutamine stress. [PDF]

Cardiovasc Ultrasound, 2020
Background Quantitative regional strain analysis by speckle tracking echocardiography (STE) may be particularly useful in the assessment of myocardial ischemia and viability, although reliable measurement of regional strain remains challenging ...

Changes in intramuscular blood flow and muscle deoxygenation at different parts of the vastus lateralis during intermittent isometric knee extension in young adult males. [PDF]

Physiol Rep
Regional differences in oxygen supply–demand balance in active muscles may be related to exercise tolerance. However, the dynamics of oxygen supply–demand balance and its regional differences within active muscles have not been clarified.

Effects of Arterial Carbon Dioxide Tension on Cerebral and Somatic Regional Tissue Oxygenation and Blood Flow in Neonates After the Norwood Procedure With Deep Hypothermic Cardiopulmonary Bypass

Frontiers in Pediatrics, 2022
Neonates undergoing the Norwood procedure for hypoplastic left heart syndrome are at higher risk of impaired systemic oxygen delivery with resultant brain, kidney, and intestinal ischemic injury, shock, and death.

Regional Myocardial Blood Flow* [PDF]

Journal of Clinical Investigation, 1967
A method is described which measures the local effectiveness of the myocardial circulation, expressed as a clearance constant. Uniform clearance constants have been demonstrated in the normal canine and human myocardium. A distinct difference in clearance constants has been demonstrated between the normal canine myocardium and areas of naturally ...

Characterization of Systemic and Regional Hemodynamics and Vascular Dysfunction in Mice with Fecal Induced Peritonitis

Biomedicines, 2022
Sepsis is associated with circulatory dysfunction contributing to disturbed blood flow and organ injury. Decreased organ perfusion in sepsis is attributed, in part, to the loss of vasoregulatory mechanisms.

Altered cerebral hemodyamics and cortical thinning in asymptomatic carotid artery stenosis. [PDF]

PLoS ONE, 2017
Cortical thinning is a potentially important biomarker, but the pathophysiology in cerebrovascular disease is unknown. We investigated the association between regional cortical blood flow and regional cortical thickness in patients with asymptomatic ...

Determination of regional bone blood flow by means of fluorescent microspheres using an automated sample-processing procedure [PDF]

, 2003
The determination of regional blood flow utilizing fluorescent microspheres (FMs) is an established method for numerous organs. Recent progress, in particular the automation of sample processing, has further improved this method.
