Rapid flow‐artifact‐free high‐resolution <scp> T <sub>2</sub> </scp> mapping via multi‐shot multiple overlapping‐echo detachment imaging
A T<sub>2</sub> mapping method with submillimeter spatial resolution and high clinical practicality is proposed and validated. Inter-shot phase variation, a nuisance factor to sequences using segmented k-space acquisition, is addressed in a navigator-free and calibrationless manner, retaining the quantification accuracy and acquisition rapidness of msh-MOLED against pulsatile CSF. This work suggests that the trajectory-related ghost artifacts may be removed through specific spatial encoding and image inpainting.
