Simultaneous Acquisition of Vessel Wall Imaging and MR Angiography in Brain MRI
Abstract
PURPOSE: The combination of vessel wall imaging (VWI) and MR angiography (MRA) is useful for differentiating between intracranial atherosclerotic disease and arterial dissection. However, additional VWI scans increase total scan time. The purpose of this study was to develop and evaluate a simultaneous acquisition method for VWI and MRA using phase-sensitive inversion recovery (PSIR) in brain MRI. METHODS: -turbo spin echo+time of flight-MRA). RESULTS: The proposed method achieved a higher contrast ratio than the conventional method. Additionally, the acquisition time was reduced to less than one-half (2 min 18 s vs 7 min 15 s). CONCLUSION: This simultaneous acquisition method using PSIR is useful for brain MRI.
