英文摘要	Visualizing implanted and/or surgical devices is crucial for interventional radiology. Conventional MRI shows the devices as dark voids or with metal artifacts. Recent methods based on susceptibility mapping using fast spin-echo sequences can offer positive contrast visualizations, but they are relatively slow. In this work, parallel acquisition and compressed sensing reconstruction are integrated to accelerate the phase-sensitive acquisition and reconstruction. Applications in brachytherapy, biopsy and stent placement are demonstrated with simulations from real data. The proposed method can increase the acquisition speed by four while preserving the images quality.
