Problems solved by technology

[0004] Often MR images are qualitative in nature: absolute image signal strength means nothing, what is interpreted is poor signal strength, contrast
This leads to subjective interpretation of images, inherent inaccuracy and user dependence

Abstract

Magnetic resonance imaging methods and apparatus for simultaneous measurement of the physical properties R1 and R2 relaxation rate, proton density, and apparent diffusion coefficient using a single magnetic resonance acquisition.

Description

technical field [0001] The present invention relates to methods, systems and computer program products for improving magnetic resonance acquisitions. In particular, the invention relates to a method for simultaneously measuring the physical property R using a single magnetic resonance acquisition 1 and R 2 Methods, systems and computer program products for relaxation rate, proton density and apparent diffusion coefficient. Background technique [0002] Magnetic resonance imaging (MRI) can produce cross-sectional images in any plane, including oblique planes. Medical MRI most often relies on the relaxation properties of excited hydrogen nuclei (protons) in water and fat. When the imaged object is placed in a strong uniform magnetic field, the spins of nuclei with non-integer spin numbers within the tissue align either parallel to the magnetic field or antiparallel. The output of the MRI scan is an MRI contrast image or a series of MRI contrast images. [0003] To underst...
