摘要： An MRI method includes: defining image regions on an object; setting imaging conditions for the defined image regions; and acquiring MR images for the image regions according to the set imaging conditions. The imaging conditions may be set by displaying information about the defined image regions and setting the imaging conditions for the image regions based on the displayed information.
