Registered quantitative susceptibility mapping image collection of mouse model concussion

A collection of spatially registered and fitted quantitative susceptibility maps of a mouse model of concussion. Multi-echo GRE-MRI (mGRE-MRI) data was acquired using a 3D multi-echo spoiled gradient recalled echo (GRE) sequence with fat saturation, flow saturation, and FOV saturation (FOV saturation boxes covering the head and neck tissues outside the imaging FOV), monopolar readout, and the following parameters: matrix size = 160 x 160 x 160, FOV size = 16 x 16 x 16 mm3, effectively resulting in a 0.1 mm3 isotropic spatial resolution, TR = 50 ms, 8 echoes with minTE/ΔTE/maxTE = 2.654/3.247/25.382 ms, flip angle = 13.5, bandwidth 400.641 Hz/px. Masked phase data from mGRE-MRI scans were used to reconstruct QSM images via STI Suite (v.3.0).33 Raw phase data were unwrapped using a Laplacian-based phase unwrapping method.34 Background phase removal was performed using the V-SHARP method35 with filter size of 6. The inverse QSM problem was solved from local tissue phase values using the iLSQR method. Data was registered using ANTs
