Abstract: Provided are a method and a magnetic resonance imaging apparatus for measuring an MR signal. The method includes: applying a radio frequency (RF) pulse to an object; acquiring, as a response to the RF pulse, a plurality of echo signals from a plurality of readout gradients formed on a gradient coil; measuring delay times of the plurality of echo signals based on points in time when the respective echo signals are acquired; and determining a gradient delay based on the plurality of delay times.

Abstract: 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.
