Mild Repetitive Head Impacts Alter Perivascular Flow in the Midbrain Dopaminergic System in Awake Rats and Increase Microgliosis and AQP4 Expression and Depolarization

This dataset contains raw MRI NIFTI images acquired for the published paper titled "Mild Repetitive Head Impacts Alter Perivascular Flow in the Midbrain Dopaminergic System in Awake Rats and Increase Microgliosis and AQP4 Expression and Depolarization". The dataset has a control group and a mild head impact group indicated by the folder name. Each subfolder has both T1-weighted axial and sagittal MRI images acquired using Fast Low Angle Shot (FLASH) sequence (TR/TE = 300/2.5ms and Flip Angle = 30°) and images were collected every 2 min and 41 sec for two hours after contrast administration. A contrast agent phantom was attached to the head coil during each scan for validation of image intensity rescaling.
