Noninvasive measurement of regional blood flow in man.

Overview

Regional blood flow in man is ideally measured by techniques that are noninvasive, accurate, and can measure flow repetitively with comparative ease. Although numerous noninvasive techniques are available, no single method records blood flow accurately in every location. The neophyte investigator is often faced with a confusing array of methods and can spend considerable time searching for the ideal one. This paper presents current methods available to the clinical or metabolic researcher and comments on the strengths and limitations of each method. It is hoped that this will allow more rapid selection of a flow measurement method that is tailored to each individual's need.
