摘要： An MRI system acquires a susceptibility-weighted image by acquiring a first RF echo signal in a first echo time for providing an image exclusive of susceptibility-weighting and acquiring a second RF echo signal in a second echo time longer than the first echo time for providing an image including susceptibility-weighting. A compensation gradient field is applied for compensating for field inhomogeneity and in response, a third RF echo signal is acquired in a third echo time longer than the second echo time. First, second and third images are generated in response to data derived from the first, second and third RF echo signals respectively and data of the first, second and third images is combined to provide image data representing an image compensating for magnetic resonance signal attenuation in the second image.

摘要： A magnetic resonance imaging apparatus and a method of acquiring a magnetic resonance image are provided. The magnetic resonance imaging apparatus includes a data acquirer configured to acquire image data of a subject based on a protocol, the protocol including a learning protocol for learning a respiration of the subject and determining an initial protocol based on the learned respiration. The magnetic resonance imaging apparatus further includes a respiratory information acquirer configured to detect the respiration of the subject, and a protocol controller configured to determine whether a respiratory cycle of the subject changes based on the detected respiration, and in response to the protocol controller determining that the respiratory cycle of the subject changes, reset the protocol based on the changed respiratory cycle.
