This study proposes a comprehensive strategy to accelerate a Radial-TSE acquisition for qualitative T2-weighted imaging and quantitative T2 mapping for body applications. A fast k-space calibration method, a radial de-streaking method based on geometric coil mixing and accelerated acquisition using multiple gradient-echo radial readout between 180° refocusing pulses were implemented. Preliminary validation in phantom and in-vivo experiments shows that the proposed method reduces the scan time of Radial-TSE by half without noticeable loss of image quality and quantification accuracy. The proposed method may allow more efficient acquisition and improve the clinical applicability of free-breathing abdominal T2 quantitative imaging.
