High Resolution TOF-MRA Using SmartSpeed-AI for the Visualization of Lenticulostriate Arteries at 3.0 T: a Preliminary Study

SmartSpeed-AI is recently introduced as a physics driven type deep learning-based novel image reconstruction technique. We investigated the utility of SmartSpeed-AI for the better visibility of lenticulostriate artery (LSA) in high spatial resolution TOF-MRA by comparing the compressed-sensing sensitivity-encoding (compressed SENSE) algorithm. Both quantitative and qualitative assessment revealed that the visibility of LSAs were significantly higher under the SmartSpeed-AI reconstruction than compressed SENSE. SmartSpeed-AI can be helpful to provide superb image quality for the depiction of small arteries like LSA in high resolution TOF-MRA.
