Evaluation of blood volume measurement techniques.
OUR STUDIES on the seeming loss of plasma from the circulation after transfusion and the mobilization of plasma often seen after hemorrhage or drug infusions have been handicapped by a large variation in measured responses between animals. Conversations with other workers on blood volume regulation have indicated that such variability is not uncommon. The necessity of using large groups of anim...

متن کاملMeasurement of Flow and Volume of Blood
One of the primary measurements the physician would like to acquire from a patient is that of the concentration of O2 and other nutrients in the cells. Such quantities are normally so difficult to measure that the doctor is forced to accept the second-class measurements of blood flow and changes in blood volume, which usually correlate with concentration of nutrients. If blood flow is difficult...
متن کاملComparison of static and dynamic MRI techniques for the measurement of regional cerebral blood volume.
Two different acquisition and processing strategies to determine the regional cerebral blood volume (rCBV) with magnetic resonance imaging (MRI) are compared. The first method is based on the acquisition of the signal time course during a bolus administration of a contrast agent (dynamic method). The second method evaluates signal changes before and after the contrast agent injection (static me...
متن کاملNewer techniques of cerebral blood flow measurement.
• A variety of methods for measuring cerebral blood flow have been developed in the past 25 years since Kety and Schmidt developed their method based on the Fick principle. None of the currently used methods approaches the clinical ideal, since none of the techniques are accurate, reproducible and noninvasive. Most accurate techniques involve catheterization of internal carotid artery and/or ju...
