title: Special techniques for imaging blood flow to tumors.
abstract: In this review, the current imaging methods of assessing tumor perfusion are discussed and compared. Because most of the techniques depend on the administration of contrast agents, we first consider some general principles underlying the fate of contrast agents and their behavior inside the unique vascular environment of tumors.
