摘要： A system improves accuracy of blood flow peak velocity measurements as well as the speed and precision of an MR data acquisition workflow. A system for blood flow velocity determination in MR imaging comprises an MR imaging system. The MR imaging system acquires a three dimensional (3D) MR imaging dataset of a patient anatomical volume of interest and a one dimensional (1D) MR imaging dataset within the volume of interest automatically aligned in response to 3D vector directional information. An image data processor derives the 3D vector directional information by, deriving velocity magnitude data using the acquired 3D MR imaging dataset, identifying maximum velocity data using the derived velocity magnitude data and transforming the identified maximum velocity data to provide the 3D vector directional information. A calculation processor uses the acquired 1D MR imaging dataset to calculate a blood flow velocity in a direction determined by the 3D vector directional information.

摘要： A system automatically concurrently performs an MR image study acquisition and supplementary image data acquisition. The system includes a detector for providing a signal indicating individual portions of an imaging scan using a first imaging method have ceased. An image data processor automatically concurrently interleaves imaging of a first anatomical portion using the first imaging method and supplementary imaging of a second anatomical portion using a different second imaging method, in response to the signal. The image data processor incorporates identifier data in data representing images acquired using the second imaging method identifying images acquired using the second imaging method differently from images acquired using the first imaging method.

摘要： A system and method is provided for magnetic resonance angiography (MRA) that includes performing a pulse sequence using the MRI system, the pulse sequence including a phase-based flow encoding to collect a time-series of image data from the portion of the vasculature of the subject and identifying at least a portion of the time series of image data corresponding to a period of reduced flow through the portion of the vasculature. The portion of the time series of image data is subtracted from the time series of image data to create a time series of images of the portion of the vasculature having background tissue surrounding the portion of the vasculature substantially suppressed.
