Acute-stroke-management needs intervention to be done within certain time-window-period. A stroke-MRI-protocol should preferably be within six minutes as reported in previous studies. Objective of this study is to design a comprehensive stroke protocol that is less than six minutes, but also includes SWI and 3D Non-contrast-MR-angio which can help in diagnosing parameters such as tissue viability, site of occlusion, collateral status, stroke-penumbra and silent microbleeds. This is achieved by using compressed-SENSE, technique that combines parallel imaging and compressed sensing by adopting balanced-sampling method, thus providing excellent time-reduction as well as adequate and diagnostic image quality.
