| 摘要 |
Methods, systems, and devices are described for substantially simultaneous acquisition of magnetic resonance angiography (MRA) and magnetic resonance venography (MRV) data. Some embodiments provide susceptibility weighted magnetic resonance imaging of vasculature, including generating a multi-echo pulse sequence having a repetition time, and a first echo and a second echo during the repetition time; acquiring MRA data from at least the first echo; and acquiring MRV data from at least the second echo. The MRA data and/or the MRV data may also be post-processed (e.g., filtered, displayed, etc.). Various embodiments provide additional functionality, including techniques for processing data from an unsampled portion of one echo using sampled data from another echo. |
