A simplified method for measuring regional blood flow.

A method of measuring regional blood flow (RBF) that is simple in procedure and calculations is described. By arresting flow promptly after a short pulse of diffusible tracer, it is feasible to equate the tracer retained in the tissue (Cfi) with that delivered by the blood. If the arterial pulse is characterized by its mean concentration (Ca) over a known duration (delta t), RBF can be estimate...

Usefulness of an Automatic Quantitative Method for Measuring Regional Cerebral Blood Flow Using 99mTc Ethyl Cysteinate Dimer Brain Uptake Ratio

 Objective(s): Improved brain uptake ratio (IBUR), employing 99mTc-ethyl cysteinate dimer (99mTc-ECD), is an automatic non-invasive method for quantitatively measuring regional cerebral blood flow (rCBF). This method was developed by the reconstruction of the theory and linear regression equation, based on rCBF measurement by H215O positron emission tomography. Clarification of differences in r...

A Method for the Estimation of Regional Cerebral Blood Flow §

Over the past years the nitrous oxide absorption method proposed by Kety and Schmidt12 has achieved wide application for the estimation of the blood flow through the cerebral tissue as a whole. However, histological evidence indicates a great variability in the relative vascularity of the several portions of the brain. Thus, for the most part, the white matter is relatively poorly supplied with...

A method for measuring cerebral hemispheric blood flow and metabolism.

A Method for Measuring Cerebral Hemispheric Blood Flow and Metabolism • A new method for measuring cerebral hemispheric blood flow together with metabolism using an injection of a 5 ml bolus of hydrogen-saturated saline into each internal carotid artery is described. This method was extensively evaluated in the monkey prior to being used in man. Under fluoroscopic control, a catheter was insert...
