Abstract

Improving spatiotemporal resolution is of great importance for dynamic MRI in clinical circumstances. An improved SPIRiT method usingartifi cial sparsity and PCA denoising is proposed in this work. Simulated cardiac perfusion phantom and in-vivo cardiac cine experiments wereconducted. The proposed method showed better image quality compared with GRAPPA and the frame-by-frame SPIRiT method.
