Effects of Contrast Agent and Outer Volume Saturation Bands on Water Suppression and Shimming of Hepatic Single-Volume Proton MR Spectroscopy at 3.0T
Figure 2
1H MRS prescan of shimming (a) and water suppression (b) acquired before and after intravenous administration of Gd-DTPA with and without outer volume saturation bands are shown. After administration of contrast agent, an important point derived from our data is the statistically significant decrease in water suppression and shimming effects. Placement of the outer volume saturation bands is helpful to improve water suppression both before and after contrast agent administration.
