Water-Fat Separation in Rat by MRI at High Field (9.4T)

Popis výsledku v původním jazyce

High fields yield benefits such as higher sensitivity along with specific problems - water-fat shift in the image or stronger susceptibility artifacts. Measurement in small animals is more problematic than in humans because the high field necessary to reach better sensitivity causes stronger susceptibility artifacts and requires shortening of specific time intervals used for encoding of the specific phase shift between water and fat. This article illustrates water and fat separation in rat at high fields. The data were acquired by a FSE-based 3-point Dixon technique employing iterative decomposition of water and fat with echo asymmetry and least-squares estimation (IDEAL) algorithm. The rat was measured in a standard volume coil. The fat/water fraction(FF, WF) map was calculated from the separated water and fat images. The results presented here show a FF map characterizing the fat distribution in a coronal slice of abdomen/pelvis region of a rat.
