The goal of MRI perfusion is to provide noninvasive estimates of functional hemodynamic parameters. The purpose of this article is to review commonly used perfusion techniques: arterial spin-labeled, dynamic susceptibility-weighted contrast and dynamic contrast-enhanced imaging. The advantages, disadvantages and limitations of each technique are discussed. Specific applications in tumor imaging are discussed in terms of determining tumor diagnosis, prognosis and treatment failure versus response.
