3.0 t magnetom verio mri system

The Siemens 3.0 T Magnetom Verio MRI system (Siemens Medical, Erlangen, Germany) with a 32-channel head coil will be used to obtain MRI data at the Affiliated Hospital of Changchun University of Chinese Medicine (Changchun, China). To avoid head movement, foam pads will be used to fix the participants’ heads. The fMRI data will be acquired with a single-shot gradient recalled echo planar imaging sequence with the following parameters: repetition time (TR)/echo time (TE) =3000 ms/30 ms, flip angle = 85, field of view (FOV) = 220 mm × 220 mm and slice thickness = 3 mm. Magnetic resonance spectroscopy (MRS) data will be acquired with 3D multivoxel proton magnetic resonance spectroscopy with the following parameters: repetition time (TR)/echo time (TE) =1750 ms/144 ms, slice thickness = 5 mm and repeat time = 128.

The Siemens 3.0 T Magnetom Verio MRI system (Siemens Medical, Erlangen, Germany) with 32-channel head coil will be used to obtain MRI data on pain relief after rESWT treatment at the Department of Radiology, Zhongshan-Xuhui Hospital, Fudan University, Shanghai, China. To avoid head movement, foam pads will be used to fix the participants’ heads. The fMRI data will be acquired with a single-shot gradient recalled echo planar imaging sequence with the following parameters: repetition time (TR)/echo time (TE) = 2530 ms/2.98 ms, flip angle = 7, field of view (FOV) = 256 mm × 256 mm and slice thickness = 1 mm. To obtain the resting fMRI data, a whole-brain blood oxygenation level-dependent (BOLD) pulse sequence (TR/TE = 2000/30 ms, flip angle = 90, FOV = 192 mm × 192 mm, voxel size = 3.0 × 3.0 × 5.0 mm, slice thickness = 1 mm and 28 slices) will be used.
