Preliminary clinical application of a fast abdomen T2 mapping technique based on single‑shot multiple overlapping‑echo acquisition

Motivation: The clinical value of newly ultrafast multiple overlapping-echo detachment T2 mapping (MOLED-T2 mapping) on common liver tumors has not yet been elucidated. Goal(s): To test the reliability of MOLED-T2 mapping in common hepatic tumors during clinical applications. Approach: Total of 23 healthy subjects and 59 patients were enrolled in our study. Free breath MOLED-T2 mapping, breath hold MOLED-T2 mapping and most used breath hold GraSE T2 mapping were compared. Results: There was no significant difference between free breath and breath hold MOLED-T2 mapping. T2 values obtained from two MOLED sequences were significantly lower than those obtained through fb-GraSE-T2 sequence. Impact: This work will stand up the foundation for subsequent research about MOLED-T2 mapping on abdomen quantitative MR imaging.
