Abstract

The article describes the determination of the amount of fat in liver tissue (steatosis) by non-invasive methods of 1H magnetic resonance (MR) spectroscopy and MR imaging in vivo on whole body tomographs. Commercially available PRESS, STEAM and HISTO techniques for 1H MR spectroscopy and 3D-Dixon techniques for MR imaging on a 3T MR tomograph were used. The accuracy and usability of individual techniques were verified on prepared lipid phantoms in the concentration range of 2.5–30% fat and on a representative group of volunteers. It turns out that MR spectroscopic and imaging methods are currently fully comparable.
