摘要： A novel model-based imaging method is proposed to enable high-resolution real time phase-contrast magnetic resonance imaging (PC-MRI) with sparse sampling. The real-time phase-contrast flow magnetic resonance imaging method comprises: acquiring real-time PC-MRI data, which includes training data and imaging data; performing a low-rank based image reconstruction, which includes estimation of temporal subspace and spatial subspace based on the acquired training data and imaging data; calculating velocity maps based on the reconstructed real-time flow images; and performing quantitative flow analysis based on the calculated velocity maps. The proposed method enables high-resolution real-time PC-MRI at 2D and for the first time at 3D without electro-cardiogram (ECG) gating and respiration control.
