Accelerating renal ASL MRI with 3D Cartesian TSE using deep learning-based Compressed SENSE.

Motivation: Motion and breathing can compromise 3D renal ASL MRI, reducing SNR and causing artifacts. Shorter-time acquisition is crucial for its clinical utilityGoal(s): To Evaluate the potential of CS-AI in accelerating renal ASL MRI with 3D Cartesian TSE. Approach: We accelerated renal ASL MRI 2-, 4-, and 6 times using CS-AI, comparing with SENSE. Results: CS-AI-accelerated images exhibited superior SNR and quality compared to SENSE, without affecting RBF quantification. Impact: This study may enhance the clinical utility of 3D renal ASL, particularly in discerning perfusion alterations in small-sized lesions like small renal masses.
