1. To describe factors the quality of arterial phase MR imaging with Gd-EOB-DTPA 2. To critically review the published literature, discuss the effects of various factors that influence Gd-EOB-DTPA arterial phase image quality, 3. To propose appropriate strategies that can help improve the arterial phase enhancement

1. Challenges for arterial phase imaging (1) Temporal mismatch & weak arterial enhancement caused by the smaller administered volume and gadolinium content of Gd-EOB-DTPA than that of conventional extracellular gadolinium contrast agents (2) Acute transient dyspnea 2. Optimization strategies (1) Modify injection protocol • Slow injection rate • Increase in administered dose • Combined use of Gd-EOB-DTPA with conventional extracellular gadolinium contrast agents (2) Optimize image acquisition • Multiple arterial phase acquisitions • Accurate scan delay determination • 3T MR (3) Avoiding acute transient dyspnea • Risk factor identification and patient education (4) Improvement in image interpretation • Subtraction images • Awareness of characteristic Gd-EOB-DTPA enhancement patterns
