摘要:
A magnetic resonance imaging (MRI) apparatus (10) acquires a plurality of parametric images (60) with at least one varying imaging parameter. A parametric map (62) is constructed from the plurality of parametric images (60). At least one pilot parameter (64) is identified from at least the parametric map (62). The at least one identified pilot parameter (64) includes at least a volume of interest for a diagnostic image. A contrast agent (54) is administered to the patient (18). The identified volume of interest is imaged during influx of the administered contrast agent (54) into the identified volume of interest. The imaging uses the at least one identified pilot parameter (64).
摘要:
A system and method of MR imaging is disclosed that includes reconstruction of MR images with uniform or homogeneous fat suppression. An imaging process is performed using partial asymmetric acquisitions in conjunction with zero-filling of k-space for dynamic contrast-enhanced imaging. Data acquisition is carried out in a relatively short period of time which reduces scan time, reduces the likelihood of subject discomfort and motion-induced artifacts, and increases patient throughput.
摘要:
A system uses a three-dimensional spoiled gradient recalled echo sequence for fat suppression with reduced total acquisition time suitable for acquiring image data under breath-hold conditions using a reversed asymmetry during data acquisition on an opposed phase echo. A system reduces RF pulse repetition time in an MR imaging pulse sequence in an MR imaging device. The system includes an RF pulse generator for generating an RF excitation pulse sequence having a pulse repetition interval. A read-out gradient magnetic field generator generates an asymmetric read-out gradient magnetic field having a readout gradient mid-point occurring prior to an RF echo pulse peak. The RF echo pulse peak is received in response to a generated RF excitation pulse.
