Effects of Contrast Agent on Water Suppression and Shimming of Kidney Single-Volume Proton MR Spectroscopy at 3.0T

Gd-DTPA exerts adverse effects on water suppression and shimming, both of which show a trend of becoming well gradually with time extension after the injection of Gd-DTPA. This phenomenon limits the diagnostic use of kidney magnetic resonance spectroscopy performed immediately after contrast-enhanced magnetic resonance imaging.
