Breast Cancer: Regional Blood Flow and Blood Volume Measured with Magnetic Susceptibility–based MR Imaging—Initial Results

Abstract

The purpose of this study was to quantify microcirculation in breast neoplasms with magnetic susceptibility-based contrast material-enhanced magnetic resonance imaging. With this imaging method for invasive cancers, the mean values of the ratios of tumor to normal blood flow and blood volume were significantly higher (P <.002) than those for benign or normal tissue. The method allows independent measurement of regional blood flow and blood volume in breast cancers.
