Quantitative T₂ mapping of abdomen has the potential for many clinical scenarios, such as for distinguishing cirrhosis and characterizing renal lesions. In this study, we applied overlapping echo acquisition together with deep learning-based reconstruction to achieving T₂ mapping of abdomen in single shot for the first time. The resulting abdominal T₂ values are in good agreement with the reported ones. This method makes high temporal resolution quantitative abdominal imaging possible, and has strong motion robustness.
