Abstract:
A simple method of obtaining consecutive H-1 and natural-abundance O-17 images is described with a scanner's original body resonator (for H-1) and a homemade linear birdcage (for O-17). 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 the B-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 combined O-17/H-1 imaging.
