The arterial phase in a liver MRI with Gadoxetate disodium(Gd-EOB-DTPA) is important in identifying and classifying focal liver lesions based on their enhancement patterns. Transient respiratory motion and truncation artifact can potentially impact the image quality of the arterial phase. These artifacts can be potentially lessened through utilizing a number of strategies, including optimized Gadoxetate disodium(Gd-EOB-DTPA) injection, appropriate timing of the arterial phase and patient instructions, and using mutli-arterial sequences.
