Abstract
OBJECTIVE: The purpose of our article is to describe the underlying physics concepts of abdominal MRI at 3.0 T and their impact on signal-to-noise ratio, susceptibility artifacts, chemical shift artifacts, and dielectric effects. CONCLUSION: Abdominal MR sequence protocols optimized for 1.5-T scanners should not be transferred to 3.0 T without substantial modification. In addition, specific patient groups--for example, large patients with ascites--are not well suited to undergo an abdominal MRI study at 3.0 T.
