Dynamic Contrast Enhanced (DCE) MRI is commonly used to detect and characterize lesions. A free-breathing DCE acquisition has high scan efficiency, but image quality can be compromised by respiratory motion. In this work, a soft-gated locally low rank parallel imaging reconstruction method is proposed for highly accelerated 3D free-breathing DCE MRI. The proposed method can significantly reduce motion artifacts, and provide high spatiotemporal resolution (approximately 1 mm 3 spatial resolution and 4 s frame rate). The proposed method has been validated on in vivo datasets.
