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 کاملMeasurement of mitral regurgitation by indicator-dilution techniques.
CONSIDERABLE progress has been made in recent years in the quantitative estimation of certain cardiovalvular abnormalities by cardiac catheterization.' The quantitative determination of mitral regurgitation has not yet reached a similar status despite a substantial amount of experimental effort. This article will give theoretical bases for determination of mitral regurgitation by indicator-dilu...
متن کاملThe measurement of segmental venous flow by an indicator dilution method.
Several methods have been evolved for the measurement of venous flow in animals, but most have a limited application in man as they involve exposure of the appropriate blood vessel. These methods include the Ludwig type stromuhr (Tigerstedt, 1892), the thermostrontuhr (Rein, 1928; Schmidt and Walker, 1935; Shipley et al., 1942), the bubble flow meter (Soskin et al., 1934; Brunner, 1948), the di...
متن کاملBedside assessment of cerebral blood flow by double-indicator dilution technique.
BACKGROUND Currently, quantitative measurement of global cerebral blood flow (CBF) at bedside is not widely performed. The aim of the present study was to evaluate a newly developed method for bedside measurement of CBF based on thermodilution in a clinical setting. METHODS The investigation was performed in 14 anesthetized patients before coronary bypass surgery. CBF was altered by hypocapni...
متن کاملBlood flow to hindquarters of steers measured by transit time ultrasound and indicator dilution.
The objective was to compare blood flow to the hindquarters of steers measured by transit time ultrasound with blood flow determined by indicator (p-aminohippurate) dilution. Five Hereford steers had ultrasonic flow probes on the abdominal aorta and catheters in the abdominal aorta and inferior vena cava inserted through both sets of circumflex iliac vessels. Indicator was infused continuously ...
