Quantification of the relative amount of water in tissue microcapillary networks

摘要

The present invention is a method for magnetic resonance (MR) imaging that causes at least two different motion enhancements due to RF / tilt pulse sequences that cause signal attenuation due to diffusion but not signal attenuation due to flow. Acquiring at least two MR images (uncorrected data) with different motion enhancement due to acquisition of two MR images (flow corrected data), RF / tilt pulse sequence causing signal attenuation due to diffusion and flow Obtaining, performing a model fit on the flow-corrected and uncorrected data, wherein at least one of the adjustable parameters is the same in both data sets Perform model fitting, which is a constraint, and Disclosed is a method directed to diffusion-perfusion, comprising obtaining quantitative information about microscopic flow by extracting at least one parameter of a Raboxel incoherent motion (IVIM) effect from a model fit .
