Combined17O/1H MRI study in a whole-body scanner
- 30 Downloads
A simple method of obtaining consecutive1H and natural-abundance17O images is described with a scanner’s original body resonator (for1H) and a homemade linear birdcage (for17O). Two kinds of experiments were performed to test the method. In the first experiment, a proton image of the phantom was acquired with a whole-body resonator. In the second experiment, the phantom was inserted into an oxygen birdcage resonator and imaged again with a whole-body resonator. The intensities of images resulting from the experiments were analyzed. Although theB 1 field homogeneity is disturbed, the proton images acquired with a whole-body resonator when the oxygen resonator is present are of acceptable quality for use in the combined17O/1H imaging.
