Abstract

Recording the washout of indicator (for example, heat, ratio-labeled dissolved gas, etc. ) transiently introduced into tissue allows the estimation of tissue blood perfusion rate. Analysis of the washout data requires a material balance which appropriately accounts for all transport mechanisms and sources and sinks of the given idicator. From that balance one may perform a sensitivity analysis which specified the susceptibility of the perfusion estimate to experimental errors in any of the pertinent parameters and variables. The sensitivity analysis is based on the normalized partial derivatives of tissue indicators concentration with respect to the experimental variables.
