title: The generalized equation for the radiotracer clearance method of measurement of regional microcirculation.
abstract: The intratissual diffusion of a tracer and the geometry of the detection system are considered and a generalization of Kety's equation for the measurement of regional microcirculation is derived. Non-monoexponential shapes of time-activity curves are examined and explained.
