Cerebral Blood Flow Methodology

چکیده
V0 is the vascular distribution volume for the tracer in the tissue. In bolus type experiments such as H2O PET, this term is significant, whereas for inhalation of Xenon, the vascular term is not generally included, and Vo = 0. To measure CBF, the free parameters in Eq 1 are varied to obtain an optimal fit of the expression to regional uptake curves, using non-linear, least squared regression analysis.

Role of Nitric Oxide and ATP-Sensitive K+ Channels in Regulation of Basal Blood Flow and Hypercapnic Vasodilatation of Cerebral Blood Vessels in Rabbit
Background: The mechanisms underlying cerebral hypercapnic vasodilatation are not fully understood. Objective: To investigate the role of nitric oxide (NO) and ATP-sensitive potassium (KATP) channels in basal blood flow regulation and hypercapnia-induced vasodilatation in rabbit cerebral blood vessels. Methods: The change in cerebral blood flow was measured by a laser Doppler flowmeter in 18 Ne...

متن کاملThe Effect of Hurdling Performance on The Adaptive Profile of Cerebral Blood Flow in Vestibular Irritation
Background: The reactions of the whole organism that occur under the action of accelerations of rectilinear and rotational motion are factors that have a systemic effect on the cerebral blood flow. The use of hurdling performance in the structure of human physical activity can have a significant impact on the tone of the brain vessels, their elasticity and venous outflow in the development of f...
متن کاملA survey of intracranial blood flow velocity in thalassemia intermedia in Khuzestan Province, Iran
Background: Beta-thalassemia intermedia (BTI) is a type of hemoglobinopathy with an increased risk of cerebrovascular accidents, and transcranial cerebral Doppler ultrasonography (TCD) through determining the mean cerebral blood flow velocity (CBFV) can serve to predict the risk of a developing stroke. This study aims to compare patients with beta-thalassemia intermedia and healthy individuals ...
متن کاملInhibition of nitric oxide synthase activity improves focal cerebral damage induced by cerebral ischemia/reperfusion in normotensive rats
Introduction: Nitric oxide seems to play a dual role in ischemia/reperfusion injury. Few studies have investigated whether it exacerbates or improves brain edema. In the present study, we inhibited the activity of nitric oxide synthase by L-NAME and evaluated the cerebral infarct volume, tissue swelling and brain edema, alongside the measurement of blood flow of the ischemic region. Methods...
متن کاملCEREBRAL BLOOD FLOW REGULATION IN ANESTHETIZED MORPHINE DEPENDENT RATS: THE ROLE OF THE ADENOSINE SYSTEM
Adenosine has many of the characteristics of a regulator of cerebral blood flow and adenosine receptors change in morphine dependency. In this study the changes in adenosine receptors' responsiveness of pial vessels in the hind limb area of the sensory cortex were evaluated in morphine dependent rats (MDR) using the laser Doppler flowmetry technique. Adult male Sprague Dawley rats (250-350 ...
