Impaired endothelial function of the retinal vasculature in hypertensive patients [PDF]

open access: yes, 2004
<p><b>Background and Purpose:</b> Arterial hypertension constitutes a central factor in the pathogenesis of stroke. We examined endothelial function of the retinal vasculature as a model of the cerebral circulation.</p> <p ...

Perfluorocarbon Enhanced Glasgow Oxygen Level Dependent (GOLD) magnetic resonance metabolic imaging identifies the penumbra following acute ischemic stroke [PDF]

open access: yes, 2018
The ability to identify metabolically active and potentially salvageable ischaemic penumbra is crucial for improving treatment decisions in acute stroke patients.

The clinical application of one-stop examination with 640-slice volume CT for Nutcracker syndrome. [PDF]

open access: yesPLoS ONE, 2013
BACKGROUND: To investigate the relationship between the level of left renal vein (LRV) compression and changes in the perfusion of the left kidney in patients with nutcracker syndrome (NCS) by one-stop whole-organ perfusion imaging of bilateral kidneys ...

Quantitative Analysis of Brain CT Perfusion in Healthy Beagle Dogs: A Pilot Study

open access: yesVeterinary Sciences, 2023
Brain computed tomography (CT) perfusion is a technique that allows for the fast evaluation of cerebral hemodynamics. However, quantitative studies of brain CT perfusion in veterinary medicine are lacking. The purpose of this study was to investigate the

Inter-study reproducibility of arterial spin labelling magnetic resonance imaging for measurement of renal perfusion in healthy volunteers at 3 Tesla [PDF]

open access: yes, 2014
Background: Measurement of renal perfusion is a crucial part of measuring kidney function. Arterial spin labelling magnetic resonance imaging (ASL MRI) is a non-invasive method of measuring renal perfusion using magnetised blood as endogenous contrast ...

Re-epithelialization of whole porcine kidneys with renal epithelial cells

open access: yesJournal of Tissue Engineering, 2017
Decellularized porcine kidneys were recellularized with renal epithelial cells by three methods: perfusion through the vasculature under high pressure, perfusion through the ureter under high pressure, or perfusion through the ureter under moderate ...

Lung Perfusion Scanning in Hepatic Cirrhosis [PDF]

open access: yesBMJ, 1972
Abnormal lung perfusion scans using radioactive particles were found in five out of six cases of hepatic cirrhosis with arterial hypoxaemia. None had clinical evidence of cardiopulmonary disease or signs of pulmonary embolism on arteriography. The scan defects are probably caused by a disorder of the pulmonary microvasculature, which may show regional ...

Neuroimaging as a selection tool and endpoint in preclinical and clinical trials [PDF]

open access: yes, 2016
Standard imaging in acute stroke enables the exclusion of non-stroke structural CNS lesions and cerebral haemorrhage from clinical and pre-clinical ischaemic stroke trials. In this review, the potential benefit of imaging (e.g., angiography and penumbral
