At present, the detection of meningeal diseases is mainly based on MRI enhanced scan sequences, however, the poor image quality of affected the degree of meninges visualization due to the limited concentration of contrast agent staying in the meningeal after administration. In this study, the feasibility of meningeal imaging with multi-echo gradient echo MR sequence (Mffe) was explored, and optimized the main scan parameters. The optimal imaging parameters were obtained by analyzing the meninge-skull signal intensity ratio (SIR) and contrast-noise ratio (CNR) of healthy volunteers.
