| Abstract | Highlights • “Perfusion” is sometimes used in a loose way to describe different aspects of blood flow • In a quantitative physiological sense, perfusion is the volume of arterial blood delivered to capillary beds within a gram of tissue per minute. • Measuring the regional delivery of labeled microspheres that stick in the capillary bed is the gold standard for measuring perfusion • Arterial spin labeling (ASL) approaches microsphere methods in a noninvasive way by magnetically tagging arterial blood • Bolus-tracking experiments, following the local delivery and clearance of an intravascular agent such as Gd-DTPA, is less sensitive to perfusion itself but provides other clinically important measurements. |
