Cerebral blood flow measured by NMR indicator dilution in cats.
We developed techniques to assess the utility of a nuclear magnetic resonance (NMR) indicator for cerebral blood flow studies in cats, using Freon-22 for the first candidate. A PIN-diode-switched NMR experiment allowed the acquisition of an arterial as well as a cerebral fluorine-19 signal proportional to concentration vs. time in a 1.89 T magnet. Mean +/- SD blood:brain partition coefficients ...
متن کاملBlood flow after retinal ischemia in cats.
PURPOSE To determine the changes in blood flow in the cat retina after 1 hour of ischemia. METHODS Blood flow in the retina and choroid of adult cats anesthetized with chloralose, acepromazine, and halothane was measured using sequential injections of radioactively labeled microspheres. Ischemia was induced by elevation of intraocular pressure above systolic arterial pressure. Measurements we...

متن کاملPET tracers and techniques for measuring myocardial blood flow in patients with coronary artery disease
Assessment of the relative distribution of myocardial flow with myocardial perfusion imaging (MPI) is methodologically limited to predict the presence or absence of flow-limited coronary artery disease (CAD). This limitation may often occur, when obstructive lesions involve multiple epicardial coronary arteries or disease-related disturbances of the coronary circulation coexist at the microvasc...
متن کاملMyocardial Blood Flow
We examined the ability of individual regions of the canine left ventricle to increase blood flow relative to baseline rates of perfusion. Regional coronary flow was measured by injecting radioactive microspheres over 90 seconds in seven anesthetized mongrel dogs. Preliminary experiments demonstrated a correlation between the regional distributions of blood flow during asphyxia and pharmacologi...
