MULTIPARAMETER PERFUSION IMAGING WITH LEAKAGE CORRECTION

摘要

A magnetic resonance imaging (MRI) methodology is provided for simultaneous measurement of dynamic susceptibility contrast (DSC) MRI and dynamic contrast enhanced (DCE) MRI perfusion and permeability parameters using a combination of dual echo and spiral acquisition techniques with no contrast agent preload. T1 and T2/T2* leakage effects are eliminated, thereby permitting accurate measurement of blood volume, blood flow and vascular permeability which are used in evaluating tumor angiogenesis.
