摘要： A magnetic resonance imaging apparatus includes a first data acquisition unit, a second data acquisition unit and an image data generating unit. The first data acquisition unit acquires first data from a slice to be a target after a first delay time from a reference of a first heart rate synchronized with an electrocardiogram. The second data acquisition unit acquires second data from the slice after a second delay time from a reference of a second heart rate which is different from the first heart rate. The image data generating unit generates image data with image reconstruction processing using the first data and the second data.

摘要： To optimize in advance a desired image quality determining pulse sequence parameter incorporated in an imaging scan, a preparation scan is adopted. The preparation scan is performed with the amount of at least one desired image quality parameter changed for each of plural preparatory images, so that a plurality of preparatory images at the desired same region of the object are acquired. For example, one such image quality parameter is TI (inversion time). The acquired preparatory scan data are processed into a plurality of preparatory images for display. A desired preparatory image is then selected from the plural preparatory images displayed, and the amount of the desired parameter used for that selected preparatory image is then set for use in the pulse sequence for a complete diagnostic imaging scan. Hence the desired image quality determining parameter of the pulse sequence is caused to have an optimum value before an actual complete diagnostic imaging scan.

摘要： A first plurality of MR signals from a patient's tissue at respectively corresponding successive first time increments extending over a first time interval including a substantial majority of a subject's cardiac cycle is acquired and analyzed to define a second time interval, shorter than the first time interval, during the cardiac cycle whereat there is a relatively steep rise in signal magnitudes as a function of time (e.g., corresponding with systole and diastole events of the cardiac cycle). A second plurality of MR signals is then acquired from tissue of the patient at respectively corresponding successive second time increments during the second time interval, the second time increments being substantially shorter than said first time increments. Image data representing at least one contrast-free image of flowing fluid vessels is generated based on the second plurality of MR signals.

摘要： A magnetic resonance imaging (MRI) system obtains an MR image of an object. The system detects an ECG signal and performs a pulse sequence of RF gradient magnetic fields toward the object. Imaging defined by the pulse sequence is longer in temporal length than one heartbeat. The system further acquires an MR signal from the object in response to performance of the pulse sequence and produces the MR image based on the acquired MR signal. Also possible are: a plurality of divided MT pulses instead of the conventional single MT pulse, an SE-system pulse sequence having a shorter echo train spacing, and the generation of sounds by applying gradient pulses incorporated in an imaging pulse sequence so as to automatically instruct a patient to perform an intermittent breath hold.

摘要： A magnetic resonance imaging (MRI) system includes an ECG detector for the patient object being imaged and an element for performing an MRI pulse sequence. An imaging unit defined by the pulse sequence is longer in temporal length than one heart beat represented by the EGG signal. An MR signal is acquired from the object in response to the pulse sequence and an MR image based on the acquired MR signal is produced. A plurality of divided MT pulses can be applied instead of the conventional single MT pulse. In this case, an SE-system pulse sequence having a shorter echo train spacing is used, to generate sounds by applying gradient pulses incorporated in an imaging pulse sequence so as to automatically instruct a patient to perform an intermittent breath hold during three-dimensional scanning.
